Abstract

The generalized bioconjugate gradient method (GBGM) and fast Fourier transform (FFT) algorithm are used for the quasi-transverse electromagnetic (TEM) analysis of generalized multistrip lines embedded in multilayered lossless/lossy, iso/anisotropic dielectric and/or magnetic media. Important computational improvement is achieved by including asymptotic extraction techniques in the determination of the spatial Green´s function matrix. Comparisons with other iterative procedures are presented. Several practical structures are analyzed and numerical results are compared with previously published data
