Abstract

An extension of the conjugate gradient (CG) method in combination with the fast Fourier transform (FFT) for the analysis of open multilayer structures is presented. Several improvements (feeding method, loading system, new basis functions for the currents) to a previous scheme have been included in the analysis method. The scheme is applied to obtain the S parameters of several structures. Results are successfully compared with experimental data from other authors. The method appears accurate and efficient. Apart from taking advantage of the memory requirements of the CG-FFT scheme the proposed method increases the speed of convergence of the same by using new basis functions.<>
