Electrodynamic modeling of irregular waveguide transmission lines with bounded nonlinear semiconductor and gyromagnetic media

摘要

Abstract: The 3D electrodynamic accuracy level models of irregular waveguiding transmission lines with nonlinear active semiconductor or gyromagnetic elements based on solving Maxwell's equations completed by equations of charge- carriers motion in a semiconductor or magnetization vector motion in a ferromagnetic are elaborated. The new decomposition approach to solve nonlinear 3D boundary electrodynamic problems for irregular waveguides is developed using nonlinear autonomous blocks. The stable numerical algorithm for determining the rigorous electrodynamic solutions corresponding to both the electromagnetic waves diffraction or the generation by nonlinear active semiconductor elements and the parametric amplification by bounded nonlinear gyromagnetic components in integrated microwave devices is created. Accurate modeling of microwave and millimeter-wave strip lines and resonators with a planar geometry Gann-effect diode or bounded nonlinear magnetized ferrite films elements is done.!11
