Multi-Wideband Terahertz Communications via Tunable Graphene-based Metasurfaces in 6G Networks
Hamidreza Taghvaee, Alexandros Pitilakis, Odysseas Tsilipakos +6
The next generation of wireless networks is expected to tap into the terahertz (0.1--10 THz) band to satisfy the extreme latency and bandwidth density requirements of future applic…
Scalability Analysis of Programmable Metasurfaces for Beam Steering
Hamidreza Taghvaee, Sergi Abadal, Alexandros Pitilakis +7
Programmable metasurfaces have garnered significant attention as they confer unprecedented control over the electromagnetic response of any surface. Such feature has given rise to…
Ultraviolet radiation impact on the efficiency of commercial crystalline silicon-based photovoltaics: A theoretical thermal-electrical study in realistic device architectures
George Perrakis, Anna C. Tasolamprou, George Kenanakis +3
We investigate and evaluate the contribution of the ultraviolet radiation spectrum on the temperature and efficiency of commercial crystalline silicon-based photovoltaics (PVs) tha…
A multi-functional reconfigurable metasurface: Electromagnetic design accounting for fabrication aspects
Alexandros Pitilakis, Odysseas Tsilipakos, Fu Liu +12
In this paper we present the theoretical considerations and the design evolution of a proof-of-concept reconfigurable metasurface, primarily used as a tunable microwave absorber, b…
Fabrication and characterization of Fused Deposition Modeling 3D printed mm-scaled metasurface units
Anna C. Tasolamprou, Despoina Mentzaki, Zacharias Viskadourakis +3
We present a cost-effective, eco-friendly and accessible method for fabricating three-dimensional, ultralight and flexible millimeter-scale metasurfaces using a household 3D printe…
Passive radiative cooling impact on commercial crystalline silicon-based photovoltaics
George Perrakis, Anna C. Tasolamprou, George Kenanakis +3
The radiative cooling of objects during daytime under direct sunlight has recently been shown to be significantly enhanced by utilizing nanophotonic coatings. Multilayer thin film…
