Journal ArticleDOI
An improved near- to far-zone transformation for the finite-difference time-domain method
TL;DR: In this paper, it was shown that the accuracy of the far-zone transformation can be further improved if the phase is compensated with respect to a second-order dispersion corrected wavenumber.
Journal ArticleDOI
Fringing fields in a liquid crystal spatial light modulator for beam steering
TL;DR: In this article, the authors reported the results of characterization, simulation and optimization of a one-dimensional liquid crystal (LC) SLM, which has a large ratio between LC layer thickness and pixel pitch that results in a fringing field between pixels.
Journal ArticleDOI
A coherent scattering model to determine forest backscattering in the VHF-band
TL;DR: The results show that, in order to determine the VHF-backscattering from a forest stand, the coherent ground interaction is an important part and has to be considered.
Proceedings ArticleDOI
Bistatic ultra-wideband SAR for imaging of ground targets under foliage
TL;DR: In this paper, the authors compared the coherent integration time and spatial resolution of bistatic and monostatic SAR with respect to the problem of detecting concealed vehicles in foliage using VHF-band SAR and showed that the vehicle-to-clutter ratio can dramatically increase by choosing different incidence angles for the transmitter and receiver.
Journal ArticleDOI
Semi-empirical modeling of apertures for shielding effectiveness simulations
TL;DR: In this paper, a semi-empirical model for complex apertures in FDTD was proposed, where instead of resolving the geometrical details of the aperture, the aperture was treated as a magnetic dipole.
