Paper Abstract

The emerging field of metasurfaces has offered unprecedented functionalities for shaping wave fronts and optical responses. Here, we realize a new class of metasurfaces with nanorod array, which can generate abrupt interfacial phase changes to control local wave front at subwavelength scale. The physical mechanism under the phase modulation is geometry phase in essence, thus can achieve broadband operation, as well as helicity-dependent property. Multiple applications have been demonstrated, such as anomalous refraction, ultrathin dual-polarity metalenses, helicitydependent unidirectional surface plasmon polariton (SPP) excitation, and three-dimensional (3D) holography.
