Superdirective Arrays with Finite-Length Dipoles: Modeling and New Perspectives
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Dense arrays can facilitate the integration of multiple antennas into finite volumes. In addition to the compact size, sub-wavelength spacing enables superdirectivity for endfire o…
Superdirective Antenna Pairs for Energy-Efficient Terahertz Massive MIMO
Konstantinos Dovelos, Stylianos D. Assimonis, Hien Quoc Ngo +1
Terahertz (THz) communication is widely deemed the next frontier of wireless networks owing to the abundant spectrum resources in the THz band. Whilst THz signals suffer from sever…
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)…
Channel Estimation and Hybrid Combining for Wideband Terahertz Massive MIMO Systems
Konstantinos Dovelos, Michail Matthaiou, Hien Quoc Ngo +1
Terahertz (THz) communication is widely considered as a key enabler for future 6G wireless systems. However, THz links are subject to high propagation losses and inter-symbol inter…
Massive MIMO with Multi-Antenna Users under Jointly Correlated Ricean Fading
Konstantinos Dovelos, Michail Matthaiou, Hien Quoc Ngo +1
We study the uplink performance of massive multiple-input multiple-output (MIMO) when users are equipped with multiple antennas. To this end, we consider a generalized channel mode…
