a, b Intensity profiles along the x–z planes at various incident wavelengths (450 nm, 500 nm, 550 nm, 600 nm, and 650 nm) through simulation and experiment, respectively. The white dotted line indicates the designed focal line. c Intensity profiles along the x–z and x–y planes when five wavelengths incident simultaneously. d Zoomed-in top-view SEM image of the fabricated meta-lens’ inverse nanostructures. e Zoomed-in top-view SEM image of the fabricated meta-lens’ solid nanostructures.
