This work presents the design of a thin planar EM lens using the double-layer sub-wavelength resonators. The performance and design of the metasurface lens are discussed, and later the MS lens is loaded to an array of three-port antennas to generate three radiation beams pointing along three directions.

This work describes the gain enhancement using a new technique of phase correction by high-low-epsilon (HLE) anisotropic media for linearly polarized antennas and the realization of media using MTMs. Read here

The technique of loading high-index slabs to a broadside CP antenna results in quadbeam radiation. Read here

Another EM routing technique, earlier used at optical frequencies, is successfully implemented at mmW frequencies for the first time to generate dual-beam radiation with single-epsilon-high (single-EH) anisotropic media. Read here
