Efficient Analysis of Inhomogeneous Dielectric Waveguides with Dielectric Strips and Microstrips Using Discrete Mode Matching Method

In this paper, the discrete mode matching (DMM) method is extended to characterize multilayered transmission line structures with inhomogeneous anisotropic dielectric layers using only 1D discretization. We have thoroughly discussed the procedure to analyze hybrid waveguides with dielectric strips and micro-strips. The analysis of the structures is based on full-wave equivalent circuit approach. It gives the generalized relation of the field components of the multilayered structure and the corresponding system equation. Accurate results are obtained with very less computational effort. The dispersion curves and the electric field intensity distribution are presented to validate the computed results
