Refocusing equations lens
WebAbstract: A procedure is derived for proper refocusing of a dielectric-filled Rotman lens with beam port locations determined according to Snell's law. The theoretical performance of such a lens is compared with that of a conventional design at wide scan angle and the design equations for correct refocusing of the refracting lens derived.
