passive to realize interference-free, power-efficient, and highly secured end-to-end wireless …

In this paper, a novel, compact, high-gain, directive, and superstrate configuration-based
metasurface (MS) antenna has been designed, which incorporates a fractal-shaped slotted …

This paper presents a novel metasurface antenna whose radiation characteristics can be
remotely controlled by optical means using PIN photodiodes. The proposed reconfigurable …

This article presents a wideband bidirectional same‐sense circularly polarized (CP) antenna
based on metasurface structure. The antenna consists of a rectangular slot and two identical …

High-directivity antenna systems that provide 2-D beam steering by rotating a pair of phase-
gradient metasurfaces (PGMs) in the near field of a fixed-beam antenna, hereafter referred …

A pattern reconfigurable metasurface antenna for an electromagnetic torso imaging system
operating at the ultrahigh frequency (UHF) band is presented. To meet the requirements of …

This article presents a hybrid metasurface split beam antenna for fifth-generation (5G)
mobile applications at 3.5 GHz. Multi-beam antennas with high directivity are required for a …

Metamaterials (MMs) are synthetic composite structures with superior properties not found in
naturally occurring materials. MMs have gained massive attention over the last two decades …

In this article, a millimeter-wave (mmW) leaky-wave antenna (LWA) with unidirectional beam
scanning (UBS) capability based on the Fabry–Perot cavity (FPC) structure is proposed for …
