Abstract:

Transformation optics is a design tool that connects the geometry of space and propagation of light.Invisibility cloaking is a corresponding benchmark example. Recent experiments at optical frequencieshave demonstrated cloaking for the light amplitude only. In this Letter, we demonstrate far-field cloakingof the light phase by interferometric microscope-imaging experiments on the previously introduced threedimensionalcarpet cloak at 700 nm wavelength and for arbitrary polarization of light.
