The Software-Defined Metasurfaces Concept and Electromagnetic Aspects
Anna C. Tasolamprou, Alexandros Pitilakis, Odysseas Tsilipakos +17
We present the concept and electromagnetic aspects of HyperSurFaces (HSFs), artificial, ultrathin structures with software controlled electromagnetic properties. The HSFs key unit…
ABSense: Sensing Electromagnetic Waves on Metasurfaces via Ambient Compilation of Full Absorption
C. Liaskos, G. Pirialakos, A. Pitilakis +13
Metasurfaces constitute effective media for manipulating and transforming impinging EM waves. Related studies have explored a series of impactful MS capabilities and applications i…
Toroidal eigenmodes in all-dielectric metamolecules
Anna C. Tasolamprou, Odysseas Tsilipakos, Maria Kafesaki +2
We present a thorough investigation of the electromagnetic resonant modes supported by systems of polaritonic rods placed at the vertices of canonical polygons. The study is conduc…
Exploration of Intercell Wireless Millimeter-Wave Communication in the Landscape of Intelligent Metasurfaces
Anna C. Tasolamprou, Alexandros Pitilakis, Sergi Abadal +19
Software-defined metasurfaces are electromagnetically ultra-thin, artificial components that can provide engineered and externally controllable functionalities. The control over th…
Dynamic Anapole in Metasurfaces made of Sculptured Cylinders
Evangelia Takou, Anna C. Tasolamprou, Odysseas Tsilipakos +1
We present all-dielectric polaritonic metasurfaces consisting of properly sculptured cylinders to sustain the dynamic anapole, i.e. a non-radiating alternating current distribution…
Joint Compressed Sensing and Manipulation of Wireless Emissions with Intelligent Surfaces
Christos Liaskos, Ageliki Tsioliaridou, Alexandros Pitilakis +8
Programmable, intelligent surfaces can manipulate electromagnetic waves impinging upon them, producing arbitrarily shaped reflection, refraction and diffraction, to the benefit of…
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…
Metasurfaces with Interleaved Electric and Magnetic Resonances for Broadband Arbitrary Group Delay in Reflection
Odysseas Tsilipakos, Thomas Koschny, Costas M. Soukoulis
Metasurfaces impart phase discontinuities on impinging electromagnetic waves that are typically limited to 0-2. Here, we show that they can break free from this limitation and s…
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…
