Reconfigurable intelligent surface (RIS) can improve the communications between a source
and a destination. Recently, continuous aperture RIS is proved to have better …

Metasurfaces have shown powerful abilities in controlling the reflections, transmissions, and
polarizations of lights or electromagnetic (EM) waves, independently. Here, we propose a …

Metasurfaces play a pivotal role in terahertz wave modulation and control. However,
persistent challenges in metasurface development include non-reusability and the …

Digital coding metasurfaces, composed of only two types of unit cells with opposite phase
responses (0 and π) that can map to the usual binary elements “0” and “1”, are capable of …

Metamaterials: Beyond Crystals, Noncrystals, and Quasicrystals is a comprehensive and
updated research monograph that focuses on recent advances in metamaterials based on …

Metasurfaces, a new class of planar metamaterial, are attracting intensive attention due to
their exceptional abilities to manipulate the electromagnetic waves. In this paper, a …

In this paper, a novel coding-based metasurface absorber (CMA) featuring a triple circular
ring resonator is introduced for broadband radar cross-section (RCS) reduction and high …

This article investigates the temporal dispersion of a wireless terahertz communication
signal caused by reflection from a rough (diffuse) surface, and its subsequent impact on …

Programmable metasurfaces have attracted significant attention in various applications such
as radar and 6G communications, owing to their ability freely shape the far-field pattern …

Meta-surfaces have been applied into various conformal reflectors for the design of a
Cassegrain system. In particular, we introduce different primary meta-surface reflectors of …
