Abstract
Metasurfaces comprise an array of meta-atoms in a stretchable polymer. The dimensions and shapes of the meta-atoms and the spacing are varied to obtain desired optical properties. Any optical wavefront, for different wavelengths, illumination angles, and polarization states can be designed with proper design of the meta-atoms. As the metasurface is stretched, the distance between the meta-atoms changes, modifying the optical response, while the dimensions of the meta-atoms remains constant.
