Beam steering performance of compressed Luneburg lens based on transformation optics

Beam steering performance of compressed Luneburg lens based on transformation optics

In this paper, two types of compressed Luneburg lenses based on transformation optics are investigated and simulated using two different sources, namely, waveguides and dipoles, which represent plane and spherical wave sources, respectively. We determined that the largest beam steering angle and the...
