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…
Flat Engineered Multi-Channel Reflectors
V. S. Asadchy, A. Diaz-Rubio, S. N. Tcvetkova +4
Recent advances in engineered gradient metasurfaces have enabled unprecedented opportunities for light manipulation using optically thin sheets, such as anomalous refraction, refle…
Perfect control of reflection and refraction using spatially dispersive metasurfaces
V. S. Asadchy, M. Albooyeh, S. N. Tcvetkova +3
Non-uniform metasurfaces (electrically thin composite layers) can be used for shaping refracted and reflected electromagnetic waves. However, known design approaches based on the g…
Metasurfaces for perfect and full control of refraction and reflection
V. Asadchy, M. Albooyeh, S. Tcvetkova +2
In this talk we present and discuss a new general approach to the synthesis of metasurfaces for full control of transmitted and reflected fields. The method is based on the use of…
Full light absorption in single arrays of spherical nanoparticles
Y. Ra'di, V. S. Asadchy, S. U. Kosulnikov +5
In this paper we show that arrays of core-shell nanoparticles function as effective thin absorbers of light. In contrast to known metamaterial absorbers, the introduced absorbers a…
Functional metamirrors
V. S. Asadchy, Y. Radi, J. Vehmas +1
Conventional mirrors obey Snell's reflection law: a plane wave is reflected as a plane wave, at the same angle. To engineer spatial distributions of fields reflected from a mirror,…
