Abstract
This paper presents an overlap algorithm applied to the nonuniform nonstandard FDTD (NS-FDTD) method in two-dimensional space. The characteristics of the overlap algorithm are numerically examined and compared with the ordinary, no overlap algorithm. The reflection rate from the boundary of two meshes using the overlap algorithm is less than -80 dB, while -30 dB for the ordinary one. Consequently, it is shown that the overlap algorithm is more suitable than using no overlap in the nonuniform NS-FDTD method
