Abstract

A three-dimensional scattering field Transmission Line Modeling (TLM) algorithm is established to obtain bistatic radar cross sections of gyroelectric and gyromagnetic objects at a single frequency. Although gyrotropic material properties are highly frequency dependent, their permittivity and permeability tensors are made of complex constants at a given frequency. For verification, the results for gyrotropic spheres are compared with those from previous studies, in which an analytical approach and the Method of Moments along with Conjugant Gradient Fast Fourier Transform method were used.
