Analysis of the effect of slot resolution on the simulating precision of thin-slot coupling with parallel implementation

This paper presents a new method with parallel FDTD algorithm based on MPI library to analyze thin-slot coupling, which often leads to huge computation. It is demonstrated that the adopted parallel strategy is feasible by comparing the results of serial FDTD computation with that of the proposed method. The high efficiency of this method is also proved. Comparison of the field components given by different slot resolutions indicates that the simulating error is huge when just several grids are used to model the slot and numerical convergence has been achieved with 15 cells/slot width.
