Abstract
The usual measure method of solution of to gyrotropic waveguide modes problem is to derive the coupled wave equations with standing wave expansion method, then solve it. Because of the difficulty of numerical realization, this method is limited to base mode problem. In this paper, we propose using the Galerkin methods which expand the EM wave in terms of simple rectangular waveguide modes, convert the mode problem to eigenvalue problem of matrix. We also present the fields distribution of eigenmodes as well as pertinent design curves.
