Intelligent Reflecting Surfaces at Terahertz Bands: Channel Modeling and Analysis
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
An intelligent reflecting surface (IRS) at terahertz (THz) bands is expected to have a massive number of reflecting elements to compensate for the severe propagation losses. Howeve…
Millimeter-wave Multimode Circular Array for Spatially Encoded Beamforming in a Wide Coverage Area
Stylianos D. Assimonis, M. Ali Babar Abbasi, Vincent F. Fusco
This paper summarizes an investigation around millimeter-wave (mmWave) multimode circular antenna array based beamformer capable of specially encoded data transmission in a wide co…
Millimeter-wave Multi-mode Circular Antenna Array for Uni-cast Multi-cast and OAM Communication
Stylianos D. Assimonis, M. Ali Babar Abbasi, Vincent Fusco
This paper investigates multi-mode and orbital angular momentum (OAM) mode data transmission techniques by a using a circular antenna array, operating at 28 GHz. The classical mode…
Two-Parametric Nyquist Pulses with Better Performance Based on Inverse Hyperbolic Functions
Songbing Liang, Stylianos D. Assimonis
In this article, three new inter-symbol interference (ISI)-free pulses with enhanced performance compared to the state-of-the-art are proposed and studied in terms of frequency and…
Intelligent Reflecting Surfaces with Spatial Modulation: An Electromagnetic Perspective
Okan Yurduseven, Stylianos D. Assimonis, Michail Matthaiou
Electromagnetic wave control using the concept of a reflecting surface is first studied as a near-field and a far-field problem. Using a secondary source present in a wireless comm…
