Optical chirality of membrane metasurfaces with broken in-plane symmetry
Ivan Toftul, Brijesh Kumar, Maxim Gorkunov +1
We study chiroptical properties of single-layer dielectric membrane metasurfaces with broken in-plane symmetry. In sharp contrast to a common belief that chiral optical phenomena r…
