Abstract

The aliasing problem in ASM-FDTD is presented in detail, to overcome the problem of the ASM-FDTD method to simulate the Electromagnetic pulse (EMP) propagation in periodic tunnel structure, the prony’s method is employed to model the time domain field of the ASM-FDTD. The solution of the aliasing problem is achieved through evaluating of the exponential models at intermediate spectral points with interpolation, and the computational resource is also saved for the later time response. The accuracy of the approach is verified by comparing the results with the MW-FDTD which is calculated by parallel computing.
