A Parallel Electromagnetic FDTD (Finite Difference - Time Domain) program is designed and implemented on JASMIN (J parallel Adaptive Structured Mesh applications INfrastructure), which is developed by Beijing Institute of Applied Physics and Computational Mathematics. By means of encapsulating high performance data structure, integrating numerical methods, masking the parallelization and adaptive meshing technology, JASMIN accelerates the development of parallel programs which can employ modern HPC (High Performance Computer) efficiently. This parallel FDTD program is full-functional with FDTD iteration, excitation, UPML (Un-split Perfect Matched Layer) absorption boundary condition, automatic load balance, etc., and is verified by computing the radiation fields of an electric dipole. As an example, the near fields of a Gaussian beam focused by a spherical lens are simulated.
