Abstract

A novel two-dimensional circular lens is presented in this paper. The mechanism of the operation of the lens is based on Gaussian optics. The focal point of the circular interface between the dielectric and air is coincident with a focal point of a hyperbolic reflector, while the feeding source is located the other focal point, which is also at the center of the circular interface. Simulations based on geometrical optics and HFSS software are presented, together with measurement results. The blockage effect of the source is addressed. The proposed design is suitable for low-cost beam steering applications.
