Abstract :
An efficient scheme for analyzing electrodynamic problems involving arbitrary metallic surfaces conformed to a circular cylinder, using the conjugate-gradient-fast-Fourier-transform (CG-FFT) method, is presented. The numerical method outlined is efficient in CPU time and minimizes the memory storage requirements. Several results are presented and compared with numerical or measured values that appear in the literature
