Abstract


The control of phase with thin metamaterial layers (metasurfaces) can play a fundamental role in generating synthetic scattering diagrams of macroscopic objects. Thin metasurfaces can introduce additional spatially non-uniform phase in the incoming wave, thereby producing non-conventional reflection and refraction of light waves. We discuss the generalized laws of reflection and refraction and overview the experimental proof-of-concept studies performed first at Harvard at a wavelength of 8 ┬Ám and then at Purdue for a broad, near-IR range.
