A Multiscale Time Integration Method for Coupled Nonlinear Electrical-Thermal Simulation

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The simulation of a coupled nonlinear electrical-thermal response in a high-power microwave (HPM) operation represents a highly multiscale problem in time. To address the temporal multiscale issue and account for the mutual coupling between the nonlinear electromagnetic (EM) response and the thermal variation, a multiscale time integration method is developed in this work. By utilizing the quasi-periodicity of the EM responses in consecutive operational cycles, the EM fields and the dissipated power calculated on the small time scale in one cycle can be extrapolated to tens of cycles away, while the thermal response is solved on its large time scale. With such a multiscale time integration, both the electrical and the thermal breakdown phenomena during the HPM operation can be captured.
