A Comparative study of the DGTD algorithm and the FVTD algorithm in Computational Electromagnetics
By calculating some typical electromagnetic problems, the performances of the FVTD algorithm and the DGTD algorithm for computational electromagnetics are compared systematically, including the choice of the time step, the numerical accuracy, the CPU time and the memory requirement The FVTD algorithm is more efficient for electrically small structure and is more accuracy for the structure with curved surface, but is not suitable for large scale electromagnetic phenomenon simulating. The DGTD is more resource consuming, but it is more accurate and has the potential ability to handle electrically large structure.
