Open publisher page 7 citations

Abstract

To simulate the EMP propagation in large-scale and long-distances vaulted tunnel, an effective MW-FDTD method based on parallel computing [1] was presented. The convolution PML (CPML) [2] is adopted to truncate the computation domain, which reduces the reflection error greatly. The accuracy and the efficiency of the proposed method have been verified by comparing the results of the parallel FDTD algorithm with the proposed method.
