Active Metasurfaces as a Platform for Capacitive Wireless Power Transfer Supporting Multiple Receivers
Fu Liu, Prasad Jayathurathnage, Sergei A. Tretyakov
As wireless power transfer (WPT) repeaters, metasurfaces can enhance field coupling, improving the WPT operation. In this paper, we show that metasurfaces can also be used as trans…
Omnidirectional Wireless Power Transfer with Automatic Power Flow Control
Prasad Jayathurathnage, Xiaojie Dang, Fu Liu +2
We present an omnidirectional wireless power transfer (WPT) system capable of automatic power flow control using three orthogonal transmitter (Tx)-repeater (Rp) pairs. The power dr…
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…
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…
Self-Oscillating Capacitive Wireless Power Transfer with Robust Operation
Fu Liu, Bhakti Chowkwale, Sergei A. Tretyakov
We show that a capacitive wireless power transfer device can be designed as a self-oscillating circuit using operational amplifiers. As the load and the capacitive wireless channel…
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…
