Abstract :
An optical metasurface providing isotropic beam refraction is reported. The metasurface consists of cascaded metallic layers which allows for complete phase control while maintaining high transmission of the co-polarized field. The efficiency of the metasurface was measured to be 3 times larger than state of the art metasurfaces consisting of a single metallic layer. Future work will consider anisotropic metasurfaces that allow both wavefront and polarization control.
