Dual angular tunability of 2D infrared notch filters: Analysis, experiments, physics
Y. H. Ko, K. J. Lee, F. A. Simlan +2
Two-dimensional (2D) resonant gratings enable dual angular tunability by controlling the plane of incidence (POI) under linear polarization. If the POI is set to be perpendicular t…
Singular states of resonant nanophotonic lattices
Y. H. Ko, K. J. Lee, F. A. Simlan +1
Fundamental effects in nanophotonic resonance systems focused on singular states and their properties are presented. Strongly related to lattice geometry and material composition,…
Perfectly-reflecting guided-mode-resonant photonic lattices possessing Mie modal memory
Yeong Hwan Ko, Nasrin Razmjooei, Hafez Hemmati +1
Resonant periodic nanostructures provide perfect reflection across small or large spectral bandwidths depending on the choice of materials and design parameters. This effect has be…
Applicability of the Rytov full effective-medium formalism to the physical description and design of resonant metasurfaces
Hafez Hemmati, Robert Magnusson
Periodic photonic lattices constitute a fundamental pillar of physics supporting a plethora of scientific concepts and applications. The advent of metamaterials and metastructures…
Band flips and bound-state transitions in leaky-mode photonic lattices
Sun-Goo Lee, Robert Magnusson
Leaky-mode photonic lattices exhibit intricate resonance effects originating in quasi-guided lateral Bloch modes. Key spectral properties are associated with phase-matched modes at…
