Microwave lenses of the waveguide type are subject to a pronounced degree of chromatic aberration because of the inherent dispersion of the waveguides. However, this aberration can be substantially eliminated over an appreciable bandwidth by making the lens of slot-loaded ridged waveguides with spec...
