Lead nanoparticles, the deep-ultraviolet to near-infrared plasmonic platform
Michael Foltýn, Michal Kvapil, Kristýna Bukvišová +2
Among the other non-noble metals, lead (Pb) is a material of particular interest for plasmonic applications in the deep ultraviolet spectral region. However, experimental studies o…
Inverse designed full-Stokes polarimetric metasurface with simultaneous wavefront sensing for visible light
OndÅej Äervinka, Martin HrtoÅ, Å tÄpán 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 KepiÄ, Petra Kalousková, Tomáš Å ikola +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…
Plasmonics of non-noble metals
Michal Horák, Michael Foltýn, Viktor Bajo +2
Localized surface plasmon resonances are self-sustained, collective oscillations of free electrons in metallic nanostructures. They have a wide range of applications. The most comm…
Tuning of Localized Surface Plasmons in Vanadium Dioxide Nanoparticles via Size and Insulator-Metal Transition
JiÅà Kabát, Rostislav Åepa, Jordan A. Hachtel +5
Vanadium dioxide has been identified as a promising phase-changing material for use in tunable plasmonic devices. In this study, we present a comprehensive modal analysis of single…
Charge reservoir as a design concept for plasmonic antennas
Rostislav Åepa, Michal Horák, Tomáš Å ikola +1
Plasmonic antennas exploit localized surface plasmons to shape, confine, and enhance electromagnetic fields with subwavelength resolution. The field enhancement is contributed to b…
