Reconfigurable intelligent surfaces (RISs) constitute the key enabler for programmable
electromagnetic propagation environments and are lately being considered as a candidate …

We devise an end-to-end (E2E) communication channel model that describes the performance
of reconfigurable intelligent surface (RIS)-assisted MIMO wireless links. The model …

A new class of Radio Frequency IDentification (RFID) tags, namely the three-dimensional (3D)-printed
chipless RFID one, is proposed, and their performance is assessed. These tags …

Reconfigurable intelligent surfaces show huge potential to provide significant performance
improvement for wireless communications. Low cost and power consumption, lightweight, …

Background: Obstructive sleep apnea syndrome and is characterized by recurrent episodes
of partial or complete upper airway collapse during sleep with consequent oxygen …

Reconfigurable intelligent surfaces are planar structures that dynamically change their
reflection or refraction behaviour to engineer complex propagation environments. A physics-…

Metasurfaces can be designed to achieve prescribed functionality. Careful meta-atom design
and arrangement achieve homogeneous and inhomogeneous layouts that can enable …

In this paper, a low-cost chipless reader for detecting depolarizing tags is described. The
reader operates in the frequency band (2–2.5) GHz, and it is compact and integrated in a single …

The optimisation of Reconfigurable Intelligent Surfaces (RIS) requires tractable channel
models that are electromagnetic compliant. We incorporate the effect of multipath fading in an …

An extension of the Uniform Geometrical Theory of Diffraction (UTD) has been recently
proposed to analyze Complex-Source Beam (CSB) diffraction by a perfectly electrically …
