Abstract
An electromagnetic-circuital-thermal multiphysics simulation method is proposed for microwave circuits with active and nonlinear devices in this paper. The discontinuous Galerkin time-domain (DGTD) equation is established based on Maxwell equation, while thermal simulation is using finite-element time-domain (FETD) method, and the lumped circuit is described by the circuit equation. Electromagnetic-circuital coupling is realized by the current and voltage of the lumped port, while electromagnetic-thermal is achieved by loss power and conductivity. At last, the method is applied to analyze the microwave amplifier.
