Slow-Wave Characteristics of Ferromagnetic Semiconductor Microstrip Line

A new slow-wave microstrip line made of a ferromagnetic semiconductor (FMS) substrate is proposed and its characteristics are discussed. Another possibility of a slow-wave microstrip line by a ferromagnetic (FM) substrate is also described in this paper. It is shown that these structures have more desirable and flexible guided wave properties than the conventional metal-insulator-semiconductor (MIS) microstrip line.
