  text: Based on the surface equivalence principle an equivalent near-field source
    can be determined by measurements with a near-field scanner. One application is
    to use the source to simulate the interferences of the device-under-test with
    other objects in its close environment. Due to a limited signal-to-noise ratio
    in practical applications, noise adds to the near-field source. Hence, noise effects
    affect the quality of the simulation results and cause uncertainties. The influence
    of the noise effects is investigated by a simulative approach with artificially
    added noise. Two test devices with different a geometric dimension, operating
    frequency and excited power are evaluated for different characteristics and signal-to-noise
    ratios to assess the impact of the simulation results. Finally, in a combined
    simulation an equivalent near-field source will disturb an IoT-device and the
    voltages at two resistors on the device are examined.

  text: In this paper, the influence of the environment on an inductive location system
    is analyzed. In the inductive location method, high frequency magnetic fields
    generated by planar coils lead to induction in other coils, which is used for
    localization analysis. Magnetic fields are not affected by changes in the dielectric
    properties of the environment, which is an advantage over other localization methods.
    However, electrical material parameters can still affect the localization results
    by indirect effects. For this reason, in this publication the influence will be
    investigated using real material parameters and their effects on the localization
    will be considered, so that the robustness and the limits of the inductive localization
    can be evaluated.

  text: In this publication a novel method for far-field prediction from magnetic
    Huygens box data based on the boundary element method (BEM) is presented. Two
    examples are considered for the validation of this method. The first example represents
    an electric dipole so that the obtained calculations can be compared to an analytical
    solution. As a second example, a printed circuit board is considered and the calculated
    far-field is compared to a fullwave simulation. In both cases, the calculations
    for different field integral equations are under comparison, and the results indicate
    that the presented method performs very well with a combined field integral equation,
    for the specified problem, when only magnetic Huygens box data is given.

  text: This paper presents a new methodology by using a multiple coil array for energy
    transmission. The complex current strengths of the transmitting coil array are
    calculated by having the knowledge about of the mutual inductances and the symmetries
    of the transmitting coil array, so that its resulting magnetic field mainly penetrates
    only the receiving coil and is strongly attenuated outside. This method is used
    for an optimized wireless energy transmission but can also be implemented for
    other inductive applications.
