Stretchable metalens with tunable focal length and achromatic characteristics

open access: yesResults in Physics, 2021
We propose a stretchable metalens on polydimethylsiloxane (PDMS) substrate. By stretching the stretchable metalens device along x- and y-axis directions, it exhibits highly tunable focal length and achromatic characteristics.
