摘　　要：A time-domain surface integral equation （TDCFIE） approach is utilized to calculate the transient scattering from arbitrarily shaped, three-dimensional dielectric bodies. In conjunction with the marching-on-in-time （MOT） method, the TDCFIE-MOT method is used to derive explicit expressions for the present-time current as a function of the incident field. Sample results showing various geometries are presented and are compared with other numerical techniques. Finally, by an incident Gaussian plane tapered wave, transient scattering from the sea surface governed by Jonswap＇s sea spectra is computed.A time-domain surface integral equation （TDCFIE） approach is utilized to calculate the transient scattering from arbitrarily shaped, three-dimensional dielectric bodies.
