Abstract :
An application of the conjugate gradient method in combination with the fast Fourier transform (CG-FFT) for the analysis of multilayer structures is presented. The first step in the process is solving the electric field integral equation (EFIE), which is done using a sampling procedure with rooftop functions to represent the induced current and pulses to average the fields. The second step is the computation of the field components at different levels of the structure. Finally, these data can be used to compute the desired parameters for microstrip circuit design purposes. Results obtained with the proposed scheme are presented.<>
