Multiphysics Modeling in Computational Electromagnetics: Technical Challenges and Potential Solutions

Share

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 example 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 final 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 and potential solutions in multiphysics modeling.
