Multiple-antenna technologies are evolving towards large-scale aperture sizes, extremely
high frequencies, and innovative antenna types. This evolution is giving rise to the …

In this letter, we consider a full-duplex (FD) space shift keying (SSK) communication system,
where information exchange between two users is assisted only by a reconfigurable …

In this paper, we investigate a practical structure of reconfigurable intelligent surface (RIS)-
based double spatial scattering modulation (DSSM) for millimeter-wave (mmWave) multiple …

Given the importance of reconfigurable intelligent surfaces (RISs) in next-generation mobile
systems, several RIS variants have been proposed in recent years. Omni-digital-RIS (omni …

Reconfigurable intelligent surface (RIS)-assisted index modulation system schemes are
considered to be a promising technology for sixth-generation (6G) wireless communication …

The pursuit of energy-efficient solutions in the context of reconfigurable intelligent surface
(RIS)-assisted wireless networks has become imperative and transformative. This paper …

In this paper, we propose a novel transmissive reconfigurable intelligent surface (TRIS)
transmitter-enabled spatial modulation (SM) multiple-input multiple-output (MIMO) system. In …

Abstract In a Reconfigurable Intelligent Surface (RIS), Mutual Coupling (MC) is unavoidable
as a result of the sub-wavelength structure of its unit elements. In addition, MC inherently …
