Abstract

In this paper, the microstrip circuit is analyzed in terms of the mixed potential integral equation (MPIE) by using of the rooftop-function expansion and the blaze-function testing technique, the integral equation is solved by the loose generalized minimal residual (LGMRES) method to accelerate iteration. Our numerical calculations show that the LGMRES can converge nearly 8 times faster than the conjugate gradient-fast Fourier transform (CG-FFT) method. A typical microstrip circuit is analyzed and the good results demonstrate the validity of the proposed algorithm.
