Abstract
Metalens Design In article number 2200268, Juntao Li, Haowen Liang, Xiao Fu, and colleagues experimentally realize a polarization-insensitive and high focus efficiency metalens at 532 nm operation for an NA = 1.48 by using dimer nano-antennas. This single layer metalens can replace a conventional objective lens and demonstrate the confocal scanning microscopic imaging with 300 nm resolution.
