Abstract

Planar multilayer structures have found several applications in electromagnetics. In this paper, an equivalent model based on the bi-characteristic-impedance transmission line (BCITL) is employed to model planar multilayer structures effectively for both lossless and lossy cases. It is found that the equivalent BCITL model provides identical results, for both perpendicular and parallel polarizations, as those obtained from the propagation matrix approach.
