Near-Perfect Conversion of a Propagating Plane Wave into a Surface Wave Using Metasurfaces
Svetlana N. Tcvetkova, Do-Hoon Kwon, Ana Díaz-Rubio +1
In this paper, theoretical and numerical studies of perfect/nearly-perfect conversion of a plane wave into a surface wave are presented. The problem of determining the electromagne…
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…
Multifunctional Cascaded Metamaterials: Integrated Transmitarrays
Amr A. Elsakka, Viktar S. Asadchy, Ihar A. Faniayeu +2
Control of electromagnetic waves using engineered materials is very important in a wide range of applications, therefore there is always a continuous need for new and more efficien…
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…
Scanning characteristics of metamirror antennas with sub-wavelength focal distance
Svetlana N. Tcvetkova, Viktar S. Asadchy, Sergei A. Tretyakov
We investigate beam scanning by lateral feed displacement in novel metasurface based reflector antennas with extremely short focal distances. Electric field distributions of the wa…
