Radio-Transparent Dipole Antenna Based on a Metasurface Cloak
Jason Soric, Younes Ra'di, Diego Farfan +1
Antenna technology is at the basis of ubiquitous wireless communication systems and sensors. Radiation is typically sustained by conduction currents flowing around resonant metalli…
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…
Broadband reflectionless metasheets: Frequency-selective transmission and perfect absorption
V. S. Asadchy, I. A. Faniayeu, Y. Ra'di +3
Energy of propagating electromagnetic waves can be fully absorbed in a thin lossy layer, but only in a narrow frequency band, as follows from the causality principle. On the other…
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,…
One-way transparent sheets
Younes Ra'di, Viktar Asadchy, Sergei Tretyakov
In this paper we introduce the concept of metasurfaces which are fully transparent when looking from one of the two sides of the sheet and have controllable functionalities for wav…
Total absorption of electromagnetic waves in ultimately thin layers
Younes Ra'di, Victor S. Asadchy, Sergei A. Tretyakov
We consider single-layer arrays of electrically small lossy bi-anisotropic particles that completely absorb electromagnetic waves at normal incidence. Required conditions for elect…
