Density of photonic states in aperiodic structures
Vladislav A. Chistyakov, Mikhail S. Sidorenko, Andrey D. Sayanskiy +1
Periodicity is usually assumed to be the necessary and sufficient condition for the formation of band gaps, i.e., energy bands with a suppressed density of states. Here, we check t…
A 2D-programmable and Scalable Reconfigurable Intelligent Surface Remotely Controlled via Digital Infrared Code
Andrey Sayanskiy, Andrey Belov, Ruslan Yafasov +4
Reconfigurable Intelligent Surfaces (RISs) are promising and relatively low-cost tools for improving signal propagation in wireless communications. An RIS assists a base station in…
Extreme Metasurfaces Enable Targeted and Protected Wireless Energy Transfer
Esmaeel Zanganeh, Polina Kapitanova, Andrey Sayanskiy +2
Controlling the electromagnetic properties of materials beyond those achievable with natural substances has become a reality with the advent of metamaterials, artificially designed…
Surface waves on self-complementary metasurfaces: intrinsic hyperbolicity, dual-directional canalization and TE-TM polarization degeneracy
Vladimir Lenets, Oleh Yermakov, Andrey Sayanskiy +4
Self-complementary metasurfaces have gained significant attention due to their unique frequency-independent transmission and reflection properties and the possibility of the polari…
Invisibility and perfect absorption of all-dielectric metasurfaces originated from the transverse Kerker effect
Hadi K. Shamkhi, Andrey Sayanskiy, Adria Canos Valero +5
Dielectric metasurfaces perform unique photonics effects and serve as the engine of nowadays light-matter technologies. Here, we suggest theoretically and demonstrate experimentall…
Metasurface engineering through bound states in the continuum
Anton S. Kupriianov, Yi Xu, Andrey Sayanskiy +3
Metasurfaces have attracted a lot of attention in recent years due to novel ways they provide for the efficient wavefront control and engineering of the resonant transmission. We d…
Controlling high-Q trapped modes in polarization-insensitive all-dielectric metasurfaces
Andrey Sayanskiy, Anton S. Kupriianov, Su Xu +4
We reveal peculiarities of the trapped (dark) mode excitation in a polarization-insensitive all-dielectric metasurface, whose unit super-cell is constructed by particularly arrangi…
Transverse scattering and generalized Kerker effects in all-dielectric Mie-resonant meta-optics
Hadi K. Shamkhi, Kseniia V. Baryshnikova, Andrey Sayanskiy +7
All-dielectric resonant nanophotonics lies at the heart of modern optics and nanotechnology due to the unique possibilities to control scattering of light from high-index dielectri…
Broadband Circular-to-Linear Polarization Conversion of Terahertz Waves Using Self-Complementary Metasurfaces
Andrey Sayanskiy, Sergei A. Kuznetsov, Daria S. Tanygina +3
In this work, we theoretically and experimentally study the conversion from a circularly polarized plane electromagnetic wave into a linearly polarized transmitted one using anisot…
Broadband Huygens' Metasurface Based on Hybrid Resonances
M. Londono, A. Sayanskiy, J. L. Araque-Quijano +2
Recently, a special class of Huygens' surfaces has been proposed which are capable of manipulation of transmitted wavefronts while exhibiting high transparency over a broad range o…
Non-scattering Metasurface-bound Cavities for Field Localization, Enhancement, and Suppression
F. S. Cuesta, V. S. Asadchy, A. D. Sayanskiy +5
We propose and analyse metasurface-bound invisible (non-scattering) partially open cavities where the inside field distribution can be engineered. It is demonstrated both theoretic…
