Switchable Wavefront of Mid-Infrared Wave Using GeSbTe Metasurfaces

Benefiting from the unprecedented superiority of phase change material on manipulating electromagnetic wave, germanium antimony telluride-based optical devices attract a lot of attention. Here, based on Pancharatnam-Berry phase, reflective metasurfaces are presented by using phase change material-ge...
