The Relation Between the Boundary Diffraction Wave Theory and Physical Optics

Abstract

The physical optics surface integral is asymptotically reduced to a line integral along the contour of the diffracting edge. It is shown that the resultant integral can be separated into two sub-integrals which represent the reflected and transmitted diffracted fields. The integrands are transformed into the same forms with the potential function of the boundary diffraction wave theory. (C) 2008 Elsevier B.V. All rights reserved.
