Maximal optical chirality via mode coupling in bilayer metasurfaces
Brijesh Kumar, Ivan Toftul, Anshuman Kumar +2
Recent advances in the physics of resonant optical metasurfaces allowed to realize the so-called maximum chirality of planar structures by engineering their geometric parameters. H…
Sensing with Broken Symmetry: Revisiting Bound States in the Continuum
Brijesh Kumar, Elizaveta Tsiplakova, Samuel John +6
Metasurface with bound states in the continuum (BICs) offer exceptional potential for optical sensing due to their inherently high quality (Q) factors. However, the detection of sy…
Dynamically Tunable Membrane Metasurfaces for Infrared Spectroscopy
Furkan Kuruoglu, Samir Rosas, Jin-Woo Cho +4
Mid-infrared spectroscopy enables biochemical sensing by identifying vibrational molecular fingerprints, but it faces limitations in instrumentation portability and analytical sens…
