Elimination of backscattering from conducting surfaces using externally loaded straight wire system

Abstract

External loaded wires are used to eliminate the scattered fields from arbitrary surfaces. The values of loads depend on the length of the external wire, the distance between the wire and the surface, the shape of the surface, the relative position of the wire with respect to the surface and the direction of the incident wave. These loads may be passive or active. The method is applied to eliminate the scattered fields from a rectangular plate and an open circular cylinder structure. The moment method is used to formulate the problem and to calculate suitable values of these loads. Elimination of the scattered field may be from one or multi-direction incident plane wave of arbitrary polarization.
