Abstract

An aplanatic lens backed by an offset conductive bowl was found to satisfy the ISO8729 passive RCS enhancer recommendation in a 12GHz scaled model across ±25°. Four wavelength radius, negative refractive index lenses composed of air or foam filled hexagonal waveguide were investigated as potential low mass and low cost alternatives to the natural plastic aplanatic lenses used in the past. The focal arc angular spread and position were studied in simulation at 9.41GHz for f/D=0.3 to f/D=1, and were found to be equivalent to the focusing ability of the prior natural plastic lenses. The maximum lens thickness was less than 1.50.
