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…
Error Analysis of Programmable Metasurfaces for Beam Steering
Hamidreza Taghvaee, Albert Cabellos-Aparicio, Julius Georgiou +1
Recent years have seen the emergence of programmable metasurfaces, where the user can modify the EM response of the device via software. Adding reconfigurability to the already pow…
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…
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…
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…
Asynchronous Circuits as an Enabler of Scalable And Programmable Metasurfaces
Loukas Petrou, Petros Karousios, Julius Georgiou
Metamaterials and metasurfaces have given possibilities for manipulating electromagnetic (EM) waves that in the past would have seemed impossible. The majority of metasurface desig…
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…
Fault Tolerance in Programmable Metasurfaces: The Beam Steering Case
Hamidreza Taghvaee, Sergi Abadal, Julius Georgiou +2
Metasurfaces, the two-dimensional counterpart of metamaterials, have caught great attention thanks to their powerful control over electromagnetic waves. Recent times have seen the…
Converting energy captured from blood flow into usable electric power: design optimisation
Maria Angelika-Nikita, Neoclis Hadjigeorgiou, Christos Manopoulos +1
In this work, we attempt to optimize the design of an electromagnetic induction device that captures the energy from the arterial wall pulsation for the purpose of powering implant…
Fault Adaptive Routing in Metasurface Controller Networks
Taqwa Saeed, Constantinos Skitsas, Dimitrios Kouzapas +8
HyperSurfaces are a merge of structurally reconfigurable metasurfaces whose electromagnetic properties can be changed via a software interface, using an embedded miniaturized netwo…
Formal Verification of a Programmable Hypersurface
Panagiotis Kouvaros, Dimitris Kouzapas, Anna Philippou +3
A metasurface is a surface that consists of artificial material, called metamaterial, with configurable electromagnetic properties. This paper presents work in progress on the desi…
