Abstract
A three-dimensional scattering field Transmission Line Modeling (TLM) algorithm is established to obtain bistatic radar cross sections of frequency dispersive gyromagnetic objects. Starting from the 1D TLM modeling of gyrotropic materials, a scattering field TLM algorithm is derived for 3D calculations. For verification, the bistatic radar cross section results for several gyromagnetic structures are compared with the single frequency computations, where the permittivity and permeability tensors are made of complex constants at a given frequency.
