Recently, gyromagnetic nonlinear transmission line (GNLTL) technology has been commonly focused on and developed rapidly as a new type of solid-state wide-spectrum high-power microwave (HPM) generation method. However, because of the lack of an efficient simulation method, its investigation and design basically rely on experiment which increases the cost and complexity. Under this situation, a simulation method based on coupled solutions of Maxwell and Landau-Lifshitz-Gilbert (LLG) equations is proposed. It can realize 2-D/3-D simulation of GNLTLs. The results of this simulation method agree well with COMSOL Multiphysics software under an uncommonly weakly nonlinear situation. This verified the validity of this method to some extent. Finally, experiments are conducted to be directly contrasted with and further verify the simulation method.
