Microwave Devices Using Anisotropic and Gyrotropic Media
In this chapter, the theory that is introduced in the previous chapters for isotropic, anisotropic and gyrotropic materials finds an application. Application examples using isotropic, anisotropic and gyrotropic materials will be introduced with detail. Most of the design examples have analytical stage involving theory of the operation, simulation stage for verification of the design and experimental stage for implementation. The device performance using these three types of materials will be compared to understand the effect of anisotropy or nonreciprocity. The devices that will be analyzed, simulated and designed including waveguides, directional couplers, microwave filters, and nonreciprocal phase shifters.
