Fast Solutions for Lossless Anisotropic Electromagnetic Scattering and Radiation Problems Using the FDTD Method
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.
