An analytical investigation of fin lines with magnetized ferrite substrate

This paper presents an analysis method of the fin line on a magnetized ferrite substrate. The method is based on the application of the network analysis techniques of electromagnetic fields (8), (9) in conjunction with the Galerkin's procedure. The determinantal equation for the propagation constant of a unilateral fin line is obtained via matrix formulation. Convergence checks are performed by increasing the number of basis functions for the representation of the aperture field. Some representative numerical results are included in the paper. The method of analysis is quite general and is applicable to other types of fin line structures containing anisotropic media.
