Fast Solutions for Lossless Anisotropic Electromagnetic Scattering and Radiation Problems Using the FDTD Method
Journal Title: Cumhuriyet Science journal - Year 2018, Vol 39, Issue 4
Abstract
In this paper, an acceleration technique is proposed to solve electromagnetic scattering and radiation problems, which contain lossless anisotropic (Lossless-ANI) materials, based on the finite-difference time-domain (FDTD) method. This technique provides a remarkable reduction in the simulation time of Lossless-ANI electromagnetic problems. A microstrip patch antenna (MPA) with a Lossless-ANI substrate, and electromagnetic scattering and radiation problems involved a Lossless-ANI scattering object are analyzed to show the performance of the acceleration technique. Numerical results show that resonant frequencies of the MPA, the bistatic radar cross section (RCS) of the scattering problem, and the directivity pattern of the radiation problem are affected by the anisotropy.
