This paper describes the implementation and estimation of a hybrid implicit-explicit (HIE)-finite-difference time-domain (FDTD) method on graphics processing unit (GPU) for massively parallel electromagnetic field simulation. The HIE-FDTD method was proposed for the analysis of the shielding effectiveness of an enclosure and is very useful for the simulation of computational domain with thin unit cell such as printed circuit board. Since the computational domain can be divided arbitrarily along the x- and y-directions in the HIE-FDTD method, this method can be suitable for the parallel computing. Thus, the HIE-FDTD method is implemented on GPU and applied to the large-scale problems. Finally, it is shown that the performance of the HIE-FDTD method on GPU is drastically superior to the HIE-FDTD method on single CPU.
