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…
From the generalized reflection law to the realization of perfect anomalous reflectors
Ana Díaz-Rubio, Viktar Asadchy, Amr Elsakka and +1
The use of the generalized Snell's law opens wide possibilities for the manipulation of transmitted and reflected wavefronts. However, known structures designed to shape reflection…
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…
