Abstract :
A conjugate gradient-fast Fourier transform (CG-FFT) scheme to analyze finite, flat, metallic patches over multilayer dielectric structures is presented. A discrete Green´s function is obtained by processing the analytical expression of this function in the spectral domain. Data for the bistatic radar cross section at normal incidence are shown for a disk of radius a with ka=10.<>
