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.
