The advances in microwave communication systems require material properties which can give optimum device performance. New materials are being developed in order to meet the requirements of design processes as technology matures. These new materials are composite mixtures of isotropic, anisotropic or gyrotropic materials. The purpose of such materials is to obtain more desirable constitutive parameters through a design process that can predict the effective properties of such a mixture. One such benefit, besides having the permittivity or permeability that exactly fits the application, is to use materials with lower cost to create a composite material that might otherwise be found in much more expensive bulk form. As a consequence, the analysis of the wave propagation through multilayered composite structures carries great importance in the development of the microwave devices with the desired material properties. If the layered structure is considered to be consisted of layered general anisotropic media, then composite mixture can be obtained by setting the desired arbitrary layer to be isotropic, electrically, magnetically gyrotropic, uniaxially or biaxially anisotropic material by changing the elements of permittivity and permeability tensors for the layered structure. In the following sections wave propagation through multilayered composite structure will be given using step by step procedure. General anisotropic medium in the composite layered structure is defined with permittivity and permeability tensors, $$ \bar{\bar{\varepsilon }} $$ and $$ \bar{\bar{\mu }} $$ , respectively.
