Reflectarrays and metasurface reflectors as diffraction gratings
Fu Liu, Do-Hoon Kwon, Sergei A. Tretyakov
Reconfigurable reflectors have a significant potential in future telecommunication systems, and approaches to the design and realization of full and tunable reflection control are…
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…
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…
Intelligent Metasurfaces with Continuously Tunable Local Surface Impedance for Multiple Reconfigurable Functions
Fu Liu, Odysseas Tsilipakos, Alexandros Pitilakis +7
Electromagnetic metasurfaces can be characterized as intelligent if they are able to perform multiple tunable functions, with the desired response being controlled by a computer in…
Multi-Channel Reflectors: Versatile Performance Experimentally Tested
S. N. Tcvetkova, V. S. Asadchy, A. Diaz-Rubio +2
We investigate multi-channel reflectors, such as a three-channel power splitter and a five-channel isolating mirror. These metasurface reflectors are able to control reflections fr…
