One of the fundamental works concerning field singularities has been proposed in 1972 [1] and states that the electromagnetic energy density must be integrable over any finite\r\ndomain, even if this domain contains singularities. It is shown, that the magnetic field \u0002H(\u0003, ϕ) and electric field \u0002E(\u0003, ϕ) are proportional to ∝ \u0003(t−1) for \u0003 → 0. The variable \u0003 is the distance to the edge and t has to fulfill the integrability condition and thus is restricted to 0 < t < 1. This result is often used to reduce the error corresponding to the singularity without increasing the numerical effort [2 - 5]. For this purpose, a correction factor K is estimated by inserting the proportionality into the wave equation. It is shown, that this method improves the accuracy of the result significantly, however the order of convergence is often not studied. In [4] a method to modify the material parameters in order to use analytic results to improve the numeric calculation is presented. In this contribution we will - inspired by the scheme given in [4] - develop a new method to estimate a correction factor for perfect conducting materials (PEC) and demonstrate the improvement of the results compared to the standard edge correction. Therefore analytic results (comparable to [1]) are consequently merged with the scheme in [4]. The main goal of this work is the calculation of the second harmonic generation (SHG) in the wave response of so-called metamaterials [6]. Frequently these structures\r\ncontain sharp metallic edges with field singularities at the interfaces which have a strong impact on the SHG signals. Thus, an accurate simulation of singularities is highly important. However, the following approach can also be applied to many other setups, and one of them is shown in the example below.","lang":"eng"}],"publication":"2010 IEEE Antennas and Propagation Society International Symposium","doi":"10.1109/aps.2010.5562017","language":[{"iso":"eng"}],"article_number":"11515155 ","date_updated":"2025-12-16T12:35:39Z","publication_status":"published","author":[{"first_name":"C","last_name":"Classen","full_name":"Classen, C"},{"full_name":"Förstner, Jens","last_name":"Förstner","orcid":"0000-0001-7059-9862","first_name":"Jens","id":"158"},{"id":"344","full_name":"Meier, Torsten","last_name":"Meier","first_name":"Torsten","orcid":"0000-0001-8864-2072"},{"full_name":"Schuhmann, R","first_name":"R","last_name":"Schuhmann"}],"publication_identifier":{"isbn":["9781424449675","9781424449682"]},"title":"Enhanced FDTD edge correction for nonlinear effects calculation","year":"2010"},{"user_id":"16199","ddc":["530"],"volume":18,"urn":"41725","_id":"4172","publisher":"The Optical Society","has_accepted_license":"1","status":"public","oa":"1","project":[{"_id":"52","name":"Computing Resources Provided by the Paderborn Center for Parallel Computing"},{"name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"file_date_updated":"2018-09-04T20:02:01Z","citation":{"chicago":"Piegdon, Karoline A., Stefan Declair, Jens Förstner, Torsten Meier, Heiner Matthias, Martin Urbanski, Heinz-Siegfried Kitzerow, et al. “Tuning Quantum-Dot Based Photonic Devices with Liquid Crystals.” <i>Optics Express</i> 18, no. 8 (2010). <a href=\"https://doi.org/10.1364/oe.18.007946\">https://doi.org/10.1364/oe.18.007946</a>.","short":"K.A.

The currents have been detected via free-space THz experiments at room temperature. Our experiments prove that Coulomb effects strongly influence injection currents. This becomes most prominently visible when exciting light-hole exciton transitions. At this photon energy we observe a pronounced phase shift of the current transients which is due to oppositely oriented heavy-hole and light-hole type contributions. We are currently developing a microscopic theory based on a 14×14 k.p model in combination with the semiconductor Bloch equations to describe the observed features quantitatively.

It is shown that the phonon-assisted tunneling is much faster (down to ∼ 6 ps even at zero temperature) in comparison with other decoherence processes. The influence of Coulomb interaction is discussed and its consequences are indicated. We calculate the relaxation rates for GaAs quantum dot molecules and study the dependence on quantum dot size, distance and offset between the constituent quantum dots.

Basic effects of Coulomb coupling regarding linear and nonlinear optical processes are discussed. By numerically solving the Heisenberg equation of motion we are able to present the temporal evolution of the system’s density matrix for a wide range of coupling parameters. The two main coupling effects in dipole approximation, biexcitonic shift and Förster energy transfer, are investigated and their qualitative and quantitative influence on absorption spectra, Rabi oscillations, and single- and two-pulse excitation is discussed.
