  text: We present a complete Visible Light Communication (VLC) system for experimental
    Vehicular VLC (V-VLC) research activities. Visible light is becoming an important
    technology complementing existing Radio Frequency (RF) technologies such as Cellular
    V2X (C-V2X) and Dedicated Short Range Communication (DSRC). In this scope, first
    works helped introducing new simulation models to explore V-VLC capabilities,
    technologies, and algorithms. Yet, experimental prototypes are still in an early
    phase. We aim bridging this gap with our system, which integrates a custom-made
    driver hardware, commercial vehicle light modules, and an Open Source signal processing
    implementation in GNU Radio, which explicitly offers rapid prototyping. Our system
    supports OFDM with a variety of Modulation and Coding Schemes (MCS) and is compliant
    to IEEE 802.11; this is in line with the upcoming IEEE 802.11 LC standard as well.
    In an extensive series of experiments, we assessed the communication performance
    by looking at realistic inter vehicle distances. Our results clearly show that
    our system supports even higher order MCS with very low error rates over long
    distances.

  text: This paper presents an area-efficient 19.25 GHz to 77 GHz frequency quadrupler
    for automotive radar applications. To reduce chip area, the delay lines of each
    doubler stage have been drastically shrunk by means of meandering, slow wave structures,
    and capacitive loading. Additional circuit techniques were applied to further
    reduce chip area. Compared to previously published Gilbert cell frequency multipliers
    the presented quadrupler achieves the shortest electrical length of the delay
    lines reported so far allowing for compact, low-cost radar transceivers. The chip
    was implemented in a IHP 130nm SiGe BiCMOS technology (f T /f max =240/340GHz).
    It dissipates 91.5mW from a 3.3V supply.

  text: "Source-free all optical sampling, based on the convolution of the signal
    spectrum\r\nwith a frequency comb in an electronic-photonic, co-integrated silicon
    device will be presented\r\nfor the first time, to the best of our knowledge.
    The method has the potential to achieve very high\r\nprecision, requires only
    low power and can be fully tunable in the electrical domain. Sampling\r\nrates
    of three and four times the RF bandwidths of the photonics and electronics can
    be achieved.\r\nThus, the presented method might lead to low-footprint, fully-integrated,
    precise, electrically\r\ntunable, photonic ADCs with very high-analog bandwidths
    for the digital infrastructure of\r\ntomorrow."

  text: Optical sampling of pseudo random microwave signals with sinc-shaped Nyquist
    pulse sequences has been demonstrated in an integrated silicon photonics platform.
    An electronic-photonic, co-integrated depletion type silicon intensity modulator
    with high extinction ratio has been used to sample the microwave signal with a
    sampling rate, which corresponds to three times its RF bandwidth. Thus, a sampling
    rate of 21 GSa/s is achieved with a 7 GHz modulator, with 3 dBm of differential
    input power.

  text: A 2nd transconductance subharmonic receiver for 245 GHz spectroscopy sensor
    applications has been proposed. The receiver consists of a 245 GHz on-chip folded
    dipole antenna, a CB (common base) LNA, a 2nd transconductance SHM (subharmonic
    mixer), and a 120 GHz push-push VCO with 1/64 divider. The receiver is fabricated
    in fT/fmax = 300/500 GHz SiGe:C BiCMOS technology. The receiver dissipates a low
    power of 288 mW. Integrated with the on-chip antenna, the receiver is measured
    on-chip with a conversion gain of 15 dB, a bandwidth of 15 GHz, and the chip will
    be utilized in PCB board design for gas spectroscopy sensor application.

  text: The terahertz frequency range provides abundant bandwidth (25GHz ~ 50 GHz)
    to achieve ultra-high-speed wireless communication and enables data rates up to
    and above 100 Gbps. We choose Parallel Sequence Spread Spectrum (PSSS) as an analog
    friendly modulation and coding scheme that allows for an efficient mixed-signal
    implementation of a 100 Gbps wireless communication system. In our system design,
    we require a DAC (Digital to Analog converters) running at 1.67 G symbols/sec.
    The optimization of the bit resolution of this DAC will considerably reduce the
    hardware implementation efforts. In this work, we presented the analytical model
    for PSSS modulation and deduced a mathematical formula to calculate the number
    of discrete level amplitudes along with their probability distribution appearing
    at the output of the PSSS modulated signal. The analytical analysis assists in
    predicting the number of the quantization level of the DAC needed at the PSSS
    transmitter. The theoretical analysis shows that there are in total 225 discrete
    levels at the output of the PSSS encoder which leads to an 8-bit resolution of
    DAC. In this paper, we analyzed the variation of BER (Bit Error Rate) to the clipping
    of low probability amplitude levels and found that there is an only slight increase
    of the BER when we clip off the low probability amplitude levels. Thus, there
    is a tradeoff involved in a minor growth of BER concerning the reduction of the
    DAC bit resolution. Finally, we can reduce the DAC bit resolution from 8 bits
    to 7 bits and thus simplify the hardware implementation efforts of DAC operating
    at 1.67 Gbps.

  text: This paper demonstrates system level analysis of an energy efficient Radio
    Frequency (RF) receiver. The receiver is based on a Surface Acoustic Wave (SAW)
    correlator which is used for highly linear demodulation and interferer suppression
    in conjunction with envelope detection for ultra-low power dissipation and hardware
    efficiency. The receiver is to be used in Wireless Sensor Networks (WSN) as a
    Wake-up Receiver (WuR) to reduce the network nodes power dissipation and provide
    asynchronous data communication. Low latency and high interference robustness
    makes this scheme interesting for industrial real-time applications. In this paper,
    the SAW correlator transfer function is derived, which functions as a Matched
    Filter (MF). Since the receiver uses envelope detection and based on the characteristic
    of the SAW, the receiver sensitivity is analyzed by means of a non-linear approach.

  text: This paper presents an approach for analog fault effect simulation automation
    based on random fault selection with a high fault coverage of the circuit under
    test by means of fault injection and simulation based on advanced sampling techniques.
    The random fault selection utilizes the likelihood of the fault occurrence of
    different electrical components in the circuit with a confidence level. Defect
    models of different devices are analyzed for the calculation of the fault probability.
    A case study with our implemented tool demonstrates that likelihood calculation
    and fault simulation provides means for efficient fault effect simulation automation.

  text: This work describes a dielectric sensing system applying a 120 GHz electrical
    interferometer for contactless permittivity measurements. The applied IC was fabricated
    in a 130 nm SiGe process featuring an ft and fmax of 240 GHz and 330 GHz. The
    on-chip system contains a 120 GHz VCO with a tuning range of 7 GHz featuring a
    divide-by-64 circuit to enable external PLL operation. An important feature of
    the IC is high-precision and high-resolution phase shifting based on a slow-wave
    transmission lines approach with digital control. This allows for direct digital
    readout ability. The on chip power detector provides DC output signals giving
    the opportunity to record transfer functions of the interferometer. It enables
    sample emulation capability by phase shift inducement in the measurement as well
    as a reference transmission line. The motherboard of the system provides PLL stabilization
    for frequency sweeps. The proposed approach is capable of automated dielectric
    monitoring by phase compensation.

  text: 'In scientific computing, unstructured meshes are a crucial foundation for
    the simulation of real-world physical phenomena. Compared to regular grids, they
    allow resembling the computational domain with a much higher accuracy, which in
    turn leads to more efficient computations.<br />There exists a wealth of supporting
    libraries and frameworks that aid programmers with the implementation of applications
    working on such grids, each built on top of existing parallelization technologies.
    However, many approaches require the programmer to introduce a different programming
    paradigm into their application or provide different variants of the code. SYCL
    is a new programming standard providing a remedy to this dilemma by building on
    standard C ++17 with its so-called single-source approach: Programmers write standard
    C ++ code and expose parallelism using C++17 keywords. The application is<br />then
    transformed into a concrete implementation by the SYCL implementation. By encapsulating
    the OpenCL ecosystem, different SYCL implementations enable not only the programming
    of CPUs but also of heterogeneous platforms such as GPUs or other devices. For
    the first time, this paper showcases a SYCL-<br />based solver for the nodal Discontinuous
    Galerkin method for Maxwell’s equations on unstructured meshes. We compare our
    solution to a previous C-based implementation with respect to programmability
    and performance on heterogeneous platforms.<br'

  text: Oblique propagation of semi-guided waves across slab waveguide structures
    with bent corners is investigated. A critical angle can be defined beyond which
    all radiation losses are suppressed. Additionally an increase of the curvature
    radius of the bends also leads to low-loss configurations for incidence angles
    below that critical angle. A combination of two bent corner systems represents
    a step-like structure, behaving like a Fabry-Perot interferometer, with two partial
    reflectors separated by the vertical height between the horizontal slabs. We numerically
    analyse typical high-index-contrast Si/SiO2 structures for their reflectance and
    transmittance properties. When increasing the curvature radius the resonant effect
    becomes less relevant such that full transmittance is reached with less critical
    conditions on the vertical distance or the incidence angle. For practical interest
    3-D problems are considered, where the structures are excited by the fundamental
    mode of a wide, shallow rib waveguide. High transmittance levels can be observed
    also for these 3-D configurations depending on the width of the rib.

  text: Semi-guided waves confined in dielectric slab waveguides are being considered
    for oblique angles of propagation. If the waves encounter a linear discontinuity
    of (mostly) arbitrary shape and extension, a variant of Snell's law applies, separately
    for each pair of incoming and outgoing modes. Depending on the effective indices
    involved, and on the angle of incidence, power transfer to specific outgoing waves
    can be allowed or forbidden. In particular, critical angles of incidence can be
    identified, beyond which any power transfer to non-guided waves is forbidden,
    i.e. all radiative losses are suppressed. In that case the input power is carried
    away from the discontinuity exclusively by reflected semi-guided waves in the
    input slab, or by semi-guided waves that are transmitted into other outgoing slab
    waveguides. Vectorial equations on a 2-D cross sectional domain apply. These are
    formally identical to the equations that govern the eigenmodes of 3-D channel
    waveguides. Here, however, these need to be solved not as an eigenvalue problem,
    but as an inhomogeneous problem with a right-hand-side that is given by the incoming
    semi-guided wave, and subject to transparent boundary conditions. The equations
    resemble a standard 2-D Helmholtz problem, with an effective permittivity in place
    of the actual relative permittivity. Depending on the properties of the incoming
    wave, including the angle of incidence, this effective permittivity can become
    locally negative, causing the suppression of propagating outgoing waves. A series
    of high-contrast example configurations are discussed, where these effects lead
    to - in some respects - quite surprising transmission characteristics.
