How good is your metalens? Experimental verification of metalens performance criterion
arXiv:2002.07425 · doi:10.1364/OL.394680
Abstract
A metric for evaluation of overall metalens performance is presented. It is applied to determination of optimal operating spectral range of a metalens, both theoretically and experimentally. This metric is quite general and can be applied to the design and evaluation of future metalenses, particularly achromatic metalenses.
