✦ Synopsis

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