Description
Summary:The Beam Mode Expansion (BME) approach for corrugated conical feed horn plus meniscus lens is presented. This approach is useful for providing the radiation pattern as it propagates through an optical system. A developed theoretical model has been verified measuring near and far field of a built horn and lens. These results have been used for designing the optical system of a Cassegrain antenna at 100 GHz using the fundamental Gaussian beam mode (GBM) of the new approach. Multi-mode analysis has been performed with the pre-designed system in order to test the fundamental GBM results.
