TL;DR: In this paper, a configuration of uniplanar compact electromagnetic band-gap (UC-EBG) structures is proposed to reduce mutual coupling between the radiating elements of an antenna array.

TL;DR: In this paper, a reflectarray antenna is used to generate and manipulate OAM-carrying laser beams at radio frequency (RF) and to tailor the antennas' far-field characteristics, such as twisted wavefront and annular-shaped intensity pattern.

TL;DR: In this article, the possibility of integration of two important categories of optical components, i.e., circular polarizer and lens, into a thin plasmonic metasurface is examined, for the realistic case when metal losses cannot be neglected, for example when operating in the visible spectrum, or at infrared when non-noble metals are used.

TL;DR: In this article, a novel method of generation and synthesis of azimuthally E-polarized vortex beams is presented, where these beams can be constructed through the interference of Laguerre-Gaussian beams carrying orbital angular momentum (OAM).

TL;DR: In this paper, a multi-band printed dipole antenna loaded with reactive elements is proposed, where the reactive loading of the dipole is inspired by the Epsilon-negative (ENG) and double negative metamaterial inclusions, which enable the loaded dipole to operate in multiuser bands.
