Abstract

This letter concentrates on an efficient time-domain integral equation (TDIE) method based on the marching-on-in-time (MOT) scheme for the analysis of the transient electromagnetic scattering from discrete body of revolution (DBOR). Taking advantage of the discrete circular symmetry, the storage requirements can be reduced significantly. Further computational efficiency can be improved by using the fast Fourier transform (FFT) technique to accelerate the matrix vector product. Numerical examples are given to validate the accuracy and efficiency of the proposed method.
