The results of an analytical and numerical investigation of TM polarized plane wave scattering from an infinite, fin-corrugated surface are presented. The surface was composed of infinitely thin, perfectly conducting fins of spacing λ/2 < a < λ. Specular reflection from this ideal surface can be completely converted to backscatter in a direction opposite to the incident wave when the fin period and height are properly chosen. A procedure is described for the design and performance prediction of a finite, fin-corrugated surface composed of finitely thick fins. Experiments performed on some optimum, nonideal surfaces under TM polarized non-plane-wave illumination indicate that they behave essentially as predicted.
