Reconfigurable intelligent surfaces (RISs) offer an entirely new route to alter the propagation
properties of electromagnetic waves and thus control their reflection, refraction, and …

Next-generation wireless networks are expected to be highly heterogeneous, multilayered,
with embedded intelligence at both the core and edge of the network. In such a context …

A reconfigurable intelligent surface (RIS) is a planar structure that is engineered to
dynamically control the electromagnetic waves. In wireless communications, RISs have …

Reconfigurable intelligent surfaces (RISs) are 2-D metasurfaces, which can intelligently
manipulate electromagnetic waves by low-cost near passive reflecting elements. RIS is …

A chirality-assisted phase is introduced to innovatively impose separate phase profiles in
two circular polarization (CP) preserving channels, namely, two co-polarized output …

In this paper, we introduce a physics-consistent analytical characterization of the free-space
path-loss of a wireless link in the presence of a reconfigurable intelligent surface. The …

Reconfigurable intelligent surface (RIS), one of the key enablers for the sixth-generation
(6G) mobile communication networks, is considered by designers to smartly reconfigure the …

Reconfigurable intelligent surfaces (RISs) have attracted major attention in the last few
years, due to their useful characteristics. An RIS is a nearly passive thin surface that can …

In this paper, we investigate the performance of an RIS-aided wireless communication
system subject to outdated channel state information that may operate in both the near-and …

Reconfigurable intelligent surface (RIS)-empowered communication, has been considered
widely as one of the revolutionary technologies for next generation networks. However, due …
