Perfect all-angle asymmetric transmission via normal susceptibilities: exact spatial derivative by local meta-atoms and nonlocal metasurfaces
Amit Shaham, Ariel Epstein
We present a systematic methodology for realizing accurate asymmetric all-angle transmission in nonlocal metasurfaces. As a representative example, we derive closed-form susceptibi…
Observation of temporal Wood's anomaly in folded time gratings: surface-wave-enhanced transmission and the emergence of gain
Amit Shaham, Ben-Zion Joselson, Ilya Varenisov +2
Wood's anomaly is a fundamental wave phenomenon that stems from the interplay between farfields and surface-wave (SW) resonances through structured interfaces. Recent theories have…
Wide-Angle Reflection Suppression of Dielectric Slabs Using Nonlocal Metasurface Coatings
Alexander Zhuravlev, Sergei Kuznetsov, Daria Kiselkina +3
Any discontinuity of constitutive parameters along a wave propagation path causes scattering. For a plane wave incident onto a flat dielectric slab, reflection becomes strongly dep…
Tracking the Evolution of Near-Field Photonic Qubits into High-Dimensional Qudits via State Tomography
Amit Kam, Shai Tsesses, Lior Fridman +10
Quantum nanophotonics offers essential tools and technologies for controlling quantum states, while maintaining a miniature form factor and high scalability. For example, nanophoto…
All-Angle Nonlocal Metasurfaces on Demand: Universal Realization of Normal Susceptibilities via Multilayered Printed-Circuit-Board (PCB) Cascades
Amit Shaham, Ariel Epstein
Embedding normal susceptibilities in metasurfaces (MS), in tandem with their tangential counterparts, greatly enriches their spatial dispersion. Particularly, judicious siphoning o…
