A comprehensive review of metamaterials and metasurfaces for wireless power transfer
(WPT) and wireless energy harvesting (WEH) is presented in this article. According to the …

Metamaterial is a kind of material/structure that is artificially designed and has exceptional
electromagnetic properties and/or other physical properties, not found in nature. A class of …

In this article, a comprehensive review specifically on the applications of rectennas for
different wireless systems has been presented. Rectenna systems are used to convert radio …

Wireless energy transmission and harvesting techniques have recently emerged as
attractive solutions to realize wireless powered networks. By eliminating fundamental power …

Mechanical antennas have attracted wide attention due to their outstanding properties of
ultra small size and low power in existing long wave communications. Here, a review of …

Metasurfaces are artificial structures that can arbitrarily manipulate electromagnetic (EM)
wavefronts. We propose a nonreciprocal EM isolating surface based on space-time-coding …

In this work, a perfect absorber based on a split ring resonator structure is proposed and
numerically analyzed. The software CST STUDIO was employed to carry out the numerical …

This paper proposes a novel design of a compact and thin metamaterials (MMs) based
wideband absorber aiming at specific microwave energy harvesting for 5G applications. The …

In this article, we present a simple and novel design of a double-sided metasurface for a
dual-band and polarization-independent microwave-energy-harvesting system. The …

In this work, we examine the potential of autonomous operation of a reconfigurable
intelligent surface (RIS) using wireless energy harvesting from information signals. To this …
