Abstract

Based on the physical optics (PO) theory, the radar cross section (RCS) of a metal sphere is numerically calculated and analyzed at high frequency limits in the Terahertz region. To obtain the relation between RCS and frequency, the scattered electric fields are estimated by using the integral equations under far field approximations for various beam widths and centers. Compared with the Mie solution of plane incident wave, RCS given by the PO theory agrees with the asymptotic values.
