In this paper, the convolution perfectly matched layer (CPML) absorbing boundary conditions (ABC) in five‐step locally one‐dimensional finite‐difference time‐domain (LOD5‐FDTD) method are deduced. The formulation of the LOD5‐FDTD is derived and numerical results are demonstrated for different Couran...
