Inverse designed full-Stokes polarimetric metasurface with simultaneous wavefront sensing for visible light
Ondřej Červinka, Martin Hrtoň, Štěpán Venos +4
Metasurfaces have emerged as a powerful platform for compact optical sensors by replacing bulky lenses with flat arrays of subwavelength nanostructures. In precision optical metrol…
Controlled dewetting and phase transition hysteresis of VO2 nanostructures
Peter Kepič, Petra Kalousková, Tomáš Šikola +1
As artificial intelligence continues to grow, so does the need for more efficient ways to process data. Besides moving from electronic to photonic circuits, a promising approach is…
Charge reservoir as a design concept for plasmonic antennas
Rostislav Řepa, Michal Horák, Tomáš Šikola +1
Plasmonic antennas exploit localized surface plasmons to shape, confine, and enhance electromagnetic fields with subwavelength resolution. The field enhancement is contributed to b…
Plasmonic properties of individual bismuth nanoparticles
Michael Foltýn, Michal Kvapil, Tomáš Šikola +1
Bismuth nanoparticles are being investigated due to their reported photothermal and photocatalytic properties. In this study, we synthesised spherical bismuth nanoparticles (50-600…
Bismuth plasmonic antennas
Michael Foltýn, Tomáš Šikola, Michal Horák
Bismuth is a particularly promising alternative plasmonic metal because of its theoretically predicted wide spectral bandwidth. In this study, we experimentally demonstrated the co…
Casimir-like effect driven self-assembly of graphene on molten metals
Kristýna Bukvišová, Radek Kalousek, Marek Patočka +8
Casimir effect, explained by Hendrik Casimir in 1948, is a macroscopic manifestation of quantum electrodynamics. Symmetry breaking due to space confinement of vacuum fluctuations i…
