Large-Scale Parallel DGTD and FETD Method for Transient Microwave Heating

With the increase of frequency and power, thermal management becomes more and more important in the design and application of RF and microwave circuits. In this paper, the microwave heating problem is studied. The discontinuous Galerkin time-domain (DGTD) method is adopted for EM simulation, while the finite-element time-domain (FETD) method is utilized for thermal simulation. The large-scale MPI parallel programming technique is used to accelerate both the DGTD and FETD method. Numerical examples are given to demonstrate the accuracy and efficiency of the proposed method.
