Future wireless systems are envisioned to create an endogenously holography-capable,
intelligent, and programmable radio propagation environment, that will offer unprecedented …

Here, we first aim to explain practical considerations to design and implement a
reconfigurable intelligent surface (RIS) in the sub-6 GHz band and then, to demonstrate its …

This is a review article discussing the latest developments in beam-steering antennas at
millimeter-wave frequencies for Beyond-5G and 6 G networks. This article classifies all the …

A novel method to synthesize a flat-topped pattern in single-curvature conformal leaky-wave
antennas (CLWAs) is presented. When synthesizing the antenna, aperture field estimation …

In this article, empty substrate integrated waveguides (ESIW) technology is applied to design
long slot leaky-wave antennas (LWAs). First, a uniform-aperture structure is presented and …

To accommodate new applications such as extended reality, fully autonomous vehicular
networks and the metaverse, next generation wireless networks are going to be subject to …

This letter presents a systematic method to regulating the response of an artificial
impedance surface. The method is based on governing the dispersion diagram to control the …

xG wireless networks require more stringent performance levels. New technologies such as
RIS and RSMA are candidates for meeting some of the performance requirements, including …

In this letter, we present a holographic metasurface (HMS) based on an orthogonally
discrete unit-cell. The proposed unit-cell possesses discrete surface impedance tuning …

In this paper, a mathematical model is proposed to govern the phase distribution on a
reconfigurable intelligent surface (RIS) for anomalously reflecting the beam towards the …
