This work presents the design of thin planar EM lens using the double layer sub-wavelength resonators. The performance and design of the metasurface lens is 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 EM routing technique is implemented to generated dual-beam radiation pattern at 28 GHz band. This routing phenomenon earlier used at optical frequencies is first time successfully implemented at mmW frequency to generate dual-beam radiation with single-epsilon-high (single-EH) anisotropic media.
