Abstract
The time-domain physical-optical (TD-PO) approximation is derived from the frequency-domain physical-optical expression by the inverse Fourier transformation. The transient scattering and RCS in a wide band of metal sphere and cube are computed. Numerical results show that TD-PO method requires relatively small amounts of computer memory and CPU time. It is an efficient algorithm for analyzing the wide band characteristic of electrically large objects
