We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

Terahertz (THz) science and technology have attracted significant attention based on their
unique applications in non-destructive imaging, communications, spectroscopic detection …

A metamaterial (MTM)-based thin planar lens antenna is proposed for spatial beamforming
and multibeam massive multiple-input multiple-output systems. The antenna consists of a …

The terahertz range is generally defined as the portion of the electromagnetic spectrum that
lies between 100 GHz and 10 THz. It is situated above the microwave range, and below the …

Ultrathin metasurface compromising various sub-wavelength meta-particles offers promising
advantages in controlling electromagnetic wave by spatially manipulating the wavefront …

An effective way for broadband holographic multiplexing based on geometric metasurfaces
is demonstrated by the integration of several recording channels into a single device. Each …

Metasurface is an artificial material composed of a series of subwavelength structure units
and has unique electromagnetic characteristics. Based on the ability of manipulating the …

We present detailed analytical modeling and in-depth investigation of wide-angle reflect-
mode metagrating beam splitters. These recently introduced ultrathin devices are capable of …

Metamaterials are an artificial electromagnetic material composed of periodic/non-periodic
subwavelength micro-/nanostructures, ie meta-atoms. The meta-atom interacts with the …

We theoretically formulate and experimentally demonstrate an analytical formalism for
designing printed circuit board (PCB) metagratings (MGs), exercising individual control over …
