Abstract: The paper presents a hybrid method based on FDTD and ADI-FDTD, introduces a method of weighted average to reduce the reflection caused by two different methods on the boundary, and presents a celerity method for the linear, lossless and isotropic medium. The simulation shows that the method is feasible. -
