How to realize achromatic metalens with varifocal performance?

The recently proposed broadband achromatic metalens (BAM) have been considered as a promising method to correct chromatic aberration in broadband imaging systems. However, these BAMs are limited to a fixed functionality that severely hinders their potential applications. In this work, the researchers focused on how ...
