A Hilbert Transform method for measuring linear and nonlinear phase shifts imparted by metasurfaces
Laura C. Wynne, Hamish T. Ballantyne, Xin Li +2
Nonlinear metasurfaces that dynamically manipulate the phase of a passing light beam are of interest for a wide range of applications. The controlled operation of such devices requ…

Diode-like asymmetric transmission in ultrathin hyperbolic epsilon-near-zero slabs: extreme anisotropy mimicking chirality
Carlo Rizza, Xin Li, Andrea Di Falco +3
We demonstrate that a strong asymmetric transmission for forward and backward propagation of tilted circular polarized optical waves is supported by ultrathin epsilon-near-zero hyp…
