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... Metalens, one of the most prominent applications of metasurface, has demonstrated the promising abilities to replace traditional lens. By manipulating the phase distribution of metalens composed of appropriately arranged meta-atoms, the wavefront of inciden...May 16, 2023 -
