Abstract :
The development of reflector-backed strip gratings exhibiting properties like the elimination of specular reflections from a conducting surface for normal and near-normal incidence is reported. This is not possibly by conventional corrugated metallic surfaces. Perfect blazing to n = ¿1 spectral order is also provided by the developed system. This technique offers a simple and inexpensive method for the simulation of corrugated horns.
