Abstract

This paper presents calculations of a new formulation of the 3D Kirchhoff approximation which allows calculation of the scattering of vector waves from 2D rough surfaces containing infinite slopes. This type of surface has applications, for example, in remote sensing and in testing or imaging of printed circuits. The equivalent 1D surface formulation is presented to introduce the method in a physically simpler form. Some preliminary calculations for rectangular-shaped grooves in a plane are presented for the 2D surface method and are compared with the equivalent 1D calculations for the Kirchhoff and integral equation methods. Good agreement is found between the methods.
