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…
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…
Generalized Huygens' condition as the fulcrum of planar nonlocal omnidirectional transparency: from meta-atoms to metasurfaces
Amit Shaham, Ariel Epstein
Fresnel reflection has been known for centuries to fundamentally impede efficient transmittance across planar interfaces, especially at grazing incidence. Herein, we present the ge…
