Topological learning for the classification of disorder: an application to the design of metasurfaces
Tristan Madeleine, Nina Podoliak, Oleksandr Buchnev +4
Structural disorder can improve the optical properties of metasurfaces, whether it is emerging from some large-scale fabrication methods, or explicitly designed and built lithograp…
Observing and Controlling a Tamm Plasmon at the Interface with a Metasurface
Oleksandr Buchnev, Alexandr Belosludtsev, Victor Reshetnyak +2
We demonstrate experimentally that Tamm plasmons in the near-IR can be supported by a dielectric mirror interfaced with a metasurface, a discontinuous thin metal film periodically…
Discriminating Between Coherent and Incoherent Light with Metasurfaces
T. Frank, O. Buchnev, T. Cookson +3
Metasurfaces represent a powerful paradigm of optical engineering that enables one to control the flow of light across material interfaces. We report on a discovery that metallic m…
Comparison of dynamic behavior of ferroelectric and ferromagnetic nematic suspensions
Nerea Sebastian, Darja Lisjak, Martin Čopič +2
The pioneering realization of suspensions of ferroelectric nanoparticles in a nematic host was one of excellent contributions of Yuri Reznikov to the science of liquid crystals [Y.…
Controlling Intensity and Phase of Terahertz Radiation with an Optically Thin Liquid Crystal-Loaded Metamaterial
O. Buchnev, J. Wallauer, M. Walther +3
We experimentally demonstrate intensity and phase modulation of terahertz radiation using actively controlled large-area planar metamaterial (metafilm) hybridized with a 12 um thic…
Orientational Coupling Amplification in Ferroelectric Nematic Colloids
Fenghua Li, Oleksandr Buchnev, Chae Il Cheon +5
We investigated the physical properties of low concentration ferroelectric nematic colloids, using calorimetry, optical methods, infra-red spectroscopy and capacitance studies. The…
