Summary:
In this paper, we analyze electrical fields reflected from concave surface scatterers by independently applying the Iterative Physical Optics (IPO) for interior region and Modified Vector Physical Optics (MPO) for exterior region. Radar cross section (RCS) is given by the radiation integral over a closed surface consisting of complementary aperture and the conducting surfaces. The high accuracy of the method is demonstrated for the RCS of an open-ended cube.
