Abstract
This paper presents calculations of a new formulation of the three‐dimensional Kirchhoff approximation which allows calculation of the scattering of vector waves from two-dimensional (2D) metal and dielectric rough surfaces containing infinite slopes. Results are presented for scattering from metal surfaces with rectangular surface structures. This type of surface has applications, for example, in remote sensing and in testing or imaging of printed circuits. Some calculations for rectangular-shaped grooves in a plane are presented for the 2D surface method and are compared to previously published results using a different method of calculation. Good agreement is found between the results for the different calculation methods.
