This presentation will cover the basic microwave properties of magnetic photonic (MPC) and degenerate bandedge (DBE) crystals both mathematically and experimentally. Two dimensional and three dimensional models will be presented demonstrating the very high sensitivity and field growth associated with the crystals. A major part of the presentation will be on the development of realistic anisotropic periodic structures using a combination of layers constructed from thin film Frequency Selective Surfaces (FSS), Alumina, Titanate and CVG materials. Measurements for antenna applications will be also presented demonstrating and validating the theoretical performance of the MPC and DBE crystrals. The latter part of the paper will present an exciting and promising development relating to microwave circuit applications. Specifically, a novel dual-line printed circuit will be presented to emulate propagation in anisotropic media. As such, the MPC and DBE phenomena can thus be created using very simple printed circuits (couple lines).
