Abstract

The biconjugate gradient-fast Fourier transform (BCG-FFT) method is a very efficient and useful technique for analyzing microstrip structures. The authors extend the BCG-FFT method to the multilayered media case using spatial domain multilayered media Green´s functions that can be obtained with the help of the discrete complex image method (DCIM). As an application, the resonant behaviour of a microstrip antenna in multilayered media is simulated using the present method combined with interpolation/extrapolation techniques. The numerical experiments for several microstrip antennas show the efficiency and accuracy of the present method
