Abstract :
Summary-A two-dimensional microwave model of the Luneberg lens has been designed employing the TE10mode. It consists of two 36-inch diameter, almost-parallel, conducting plates with the space between plates filled with polystyrene. Its thickness varies with the normalized radius, T, to give the desired index of refraction n = \\sqrt {2-r_2} Due to symmetrp about the center, this lens maintains constant gain and beam shape as a feed is scanned over its circumference, while the side lobe level remains at least 18 db below peak power. Experimental patterns show good agreement with computed patterns in the two principal planes.
