Analysis of corrugated soft edges to reduce scattering from gaps between reflecting panels

A technique to reduce scattering from gaps between reflecting panels by using the concept of soft surfaces is described, as well as a computer program to analyze it. The computer program has been developed for the analysis of a two-dimensional gap in an infinitely large and perfectly conducting ground plane. The edges of the ground plane can be provided with an arbitrary number of corrugations inside the gap, with arbitrary rectangular shapes. This computer code is used to analyze different geometries in order to look for increased bandwidth. The program has been used to construct corrugations of different depth that reduce the transmission through a gap over a bandwidth of 4:1.<>
