Abstract :
In this paper, the parallel and distributed FDTD (Finite-Difference Time-Domain) -based electromagnetic field solver is implemented on the PC cluster and multi-core CPUs system with MPI(message passing interface). In the FDTD method, the space including the object to be analyzed is divided to an enormous number of meshes. Although in general, the FDTD-based transient simulation is a time consuming task for the large scale space, FDTD method is a suitable technique for parallel computing because the electric and magnetic fields are updated with time progress using only adjacent electromagnetic variables. In this research, some electromagnetic simulations of the 2-D free space are performed by parallel computing method and the validity of this method is verified.
