Efficient Circular Polarized Metamaterial RF Energy Harvester for Wi-Fi Applications
Stylianos D. Assimonis, Vincent Fusco, Manos M. Tentzeris
A new metamaterial based, circular polarized electromagnetic energy harvester is presented in this work. The structure, which is multilayer and utilises the well-known to the liter…
Intelligent Reflecting Surface-Aided Wideband THz Communications: Modeling and Analysis
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
In this paper, we study the performance of wideband terahertz (THz) communications assisted by an intelligent reflecting surface (IRS). Specifically, we first introduce a generaliz…
Electromagnetic Modeling of Holographic Intelligent Reflecting Surfaces at Terahertz Bands
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +2
Intelligent reflecting surface (IRS)-assisted wireless communication is widely deemed a key technology for 6G systems. The main challenge in deploying an IRS-aided terahertz (THz)…
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…
