Pseudochirality at exceptional rings of optical metasurfaces

R Kolkowski, S Kovaios, AF Koenderink - Physical Review Research, 2021 - APS
Non-Hermitian optical metasurfaces have recently attracted interest as a platform for
controlling light in amplitude, phase, and polarization. Here we predict that breaking parity …
