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,…
Metamirrors
Viktar Asadchy, Younes Radi, Sergei Tretyakov
We introduce the concept of non-uniform metamirrors (full-reflection metasurfaces) providing full control of reflected wave fronts independently from the two sides of the mirror. M…
A Single-Layer Meta-Atom Absorber
Ihar Faniayeu, Viktar Asadchy, Tatsyana Dziarzhauskaya +2
We realized and experimentally tested a conceptually new kind of electrically thin absorbers of electromagnetic waves. The idea is to utilize a single layer of precisely designed m…
Polarizabilities of nonreciprocal bianisotropic particles
M. S. Mirmoosa, Y. Ra'di, V. S. Asadchy +2
For two electrically small nonreciprocal scatterers an analytical electromagnetic model of polarizabilities is developed. Both particles are bianisotropic: the so-called Tellegen-o…
Determining polarizability tensors for an arbitrary small electromagnetic scatterer
Viktar S. Asadchy, Igar A. Faniayeu, Younes Ra'di +1
In this paper, we present a method to retrieve tensor polarizabilities of general bi-anisotropic particles from their far-field responses to plane-wave illuminations. The necessary…
Tailoring reflections from thin composite metamirrors
Y. Ra'di, V. S. Asadchy, S. A. Tretyakov
We propose an effective route to fully control the phase of plane waves reflected from electrically (optically) thin sheets. This becomes possible using engineered artificial full-…
