Plasmonic structure integrated superconducting nanowire single-photon detector with BSCCO stripes
András Szenes, László Pothorcki, Balázs Bánhelyi +1
Superconducting nanowire single-photon detectors (SNSPDs) were integrated with plasmonic nanostructures to enhance the absorption efficiency of superconducting BSCCO stripes. A num…
Multilayer Babinet metamaterial to initiate nonreciprocal topological phenomena and generalized Faraday rotation
Balázs Bánhelyi, Miklós Waldhauser, Virág Szünstein +8
Multilayers of Babinet complementary periodic structures constructed with miniarrays of spherical plasmonic nanoresonators were optimized to ensure Generalized Faraday Rotation. No…
No Soundness in the Real World: On the Challenges of the Verification of Deployed Neural Networks
Attila Szász, Balázs Bánhelyi, Márk Jelasity
The ultimate goal of verification is to guarantee the safety of deployed neural networks. Here, we claim that all the state-of-the-art verifiers we are aware of fail to reach this…
Layered Babinet complementary patterns acting as asymmetric negative index metamaterial
Emese Tóth, Olivér A. Fekete, Balázs Bánhelyi +1
Azimuthal orientation and handedness dependence of the optical responses, accompanied by asymmetric transmission and asymmetric dichroism, were demonstrated on multilayers construc…
Plasmonic nanoprism distributions to promote enhanced and uniform energy deposition in passive and active targets
Dávid Vass, Emese Tóth, András Szenes +6
Passive and active targets, implanted with gold nanoprisms, were designed to achieve enhanced and uniform power absorption during two-sided illumination by short laser pulses. The…
Lasing and spasing with active individual core-shell plasmonic nanoresonators
Dávid Vass, András Szenes, Péter Zoltán Nagy +2
Active core-shell nanoresonators were designed in order to achieve large near-field enhancement, large power-outflow and minimal spaser threshold in the pump E-field strength. Gain…
