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…
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…
Chua Mem-Components for Adaptive RF Metamaterials
J. Georgiou, K. M. Kossifos, A. H. Jaafar +2
Chua's mem-components are ideal for creating adaptive metasurfaces for manipulating EM waves given that they hold their state without external biases. In this paper, we propose a g…
An Optically-Programmable Absorbing Metasurface
K. M. Kossifos, A. H. Jaafar, N. T. Kemp +2
A tunable metasurface absorber is presented in this work using an optically-programmable capacitor as the tuning element. The tuning element does not employ conventional semiconduc…
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…
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…
