Abstract

In this paper, we reviewed some recent studies on planar metamaterials and demonstrated two new way to realize high directive antenna for the first time: 1) Quasi-periodic metamaterial surface can suppress transverse-electric (TE) surface waves and support directive emissions. 2) Periodic metamaterial surface can be applied in realizing one-dimensional subwavelength Fabry-Perrot (FP) metamaterial cavity which support directive emissions. We show both experimentally and theoretically that these phenomena mainly originate from the dispersive reflection phase and surface wave dispersions.
