An efficient nonlinear frequency multiplication mechanism in ferrite loaded waveguide structures

In this paper, we have carried out the rigorous nonlinear analysis of propagating waves in the waveguiding structure (WGS), loaded with a ferrite, having a "strong" nonlinearity, using nonlinear Maxwell\´s equations formulation, complemented by the equation of motion of the magnetization vector in a ferromagnet. We have created computing algorithms, using the numerical methods of nonlinear autonomous blocs for modeling and CAD of microwave devices. This algorithm was used in the present paper. The mathematical simulation is based on the solution of diffraction boundary problems for nonlinear Maxwell\´s equations.
