Lecture  Abstract

As  computational methods for solving Maxwell’s equations become mature, the time  has come to tackle much more challenging multiphysics problems, which have a  great range of applications in sciences and technologies. In this presentation,  we will use five examples to illustrate the nature and modeling of multiphysics  problems. The first example is related to electromagnetic hyperthermia, which  requires solving electromagnetic and bio-heat transfer equation for the  planning and optimization of the treatment process. The second concerns the  heat problem in integrated circuits due to electromagnetic dissipated power,  which requires an electrical-thermal co-simulation. The third example considers  modeling of monolithic microwave integrated circuits, which consist of both  distributive and lumped circuit components. The fourth is the simulation of  vacuum electronic devices using the particle-in-cell method, which solves  Maxwell’s equations and particle kinetic equation, and the last example  simulates the air and dielectric breakdown in high-power microwave devices by  coupling electromagnetic modeling with various plasma models. With these  examples, we will discuss the methodologies and some of the challenges in  multiphysics modeling.
