Stress-transfer from polymer substrates to monolayer and few-layer graphenes
Ch. Androulidakis, D. Sourlantzis, E. N. Koukaras +2
In the present study the stress transfer mechanism in graphene-polymer systems under tension is examined experimentally using the technique of laser Raman microscopy. We discuss in…
Electromagnetic Aspects of Practical Approaches to Realization of Intelligent Metasurfaces
Fu Liu, Odysseas Tsilipakos, Xuchen Wang +9
We thoroughly investigate the electromagnetic response of intelligent functional metasurfaces. We study two distinct designs operating at different frequency regimes, namely, a swi…
Tunable Perfect Anomalous Reflection in Metasurfaces with Capacitive Lumped Elements
Odysseas Tsilipakos, Fu Liu, Alexandros Pitilakis +8
We demonstrate tunable perfect anomalous reflection with metasurfaces incorporating lumped elements. The tunable capacitance of each element provides continuous control over the lo…
Software-Defined Metasurface Paradigm: Concept, Challenges, Prospects
Alexandros Pitilakis, Anna C. Tasolamprou, Christos Liaskos +13
HyperSurfaces (HSFs) are devices whose electromagnetic (EM) behavior is software-driven, i.e., it can be defined programmatically. The key components of this emerging technology ar…
On the Calculation of the Quality Factor in Contemporary Photonic Resonant Structures
Thomas Christopoulos, Odysseas Tsilipakos, Georgios Sinatkas +1
The correct numerical calculation of the resonance characteristics and, principally, the quality factor of contemporary photonic and plasmonic resonant systems is of utmost imp…
