Full‐wave equivalent circuit for the analysis of multilayered microwave structures with anisotropic layers

A simple formalism is presented as a basis to analyse planar microwave structures with uniaxial anisotropic materials having either electric or magnetic anisotropy or both. It involves a generalised relation of the field components of the multilayered structure, which can be represented by a full‐wave hybrid matrix for each layer. Thus, for stratified structures, the system equation can be obtained by using a full‐wave equivalent circuit. The application is demonstrated by analysing the well‐known example of a two‐layer waveguide filled with different uniaxial anisotropic dielectric material.
