A Speeding Up Technique for Lossy Anisotropic Algorithm in FDTD Method

Abstract

In this paper, a speeding up technique for the lossy anisotropic (Lossy-ANI) algorithm integrated into the finite-difference time-domain (FDTD) method is proposed. The speeding up technique provides remarkable reduction in the computation time of the Lossy-ANI algorithm. This algorithm is applied to a line-fed microstrip patch antenna (MPA) with anisotropic substrate and a lossy anisotropic scattering object. Numerical results show that the anisotropy effects the resonant frequencies of the MPA and the bistatic RCS of the scattering object.
