Meta-Optics Based on Plasmonics and Geometry Phase(3/3)

The aim of this project is to develop a meta-optic system basedplasmonics and geometry phase. It has been demonstrate versatile metadeviceswith extraordinary optical properties based onmetamaterials/metasurfaces. In this project, we are going to integratemeta-devices with traditional optical system to be a meta-optic system.This project is a three years one. For 1st year, a broadband metasurfacewith 2p phase modulation in microwave regime will be designed,fabricated and measured. We will setup a microwave measurement systemfor measuring the far-field / near-field properties of metasurfaces.Transmission/reflection spectrum, phase modulation, and localized fieldof the microwave metasurface will be measured. For 2nd year, a broadbandpolarization-independent meta-corrector in visible range will bedemonstrated for eliminating the aberrations of an optical system. Theoptical performance of the optical system will be evaluated as well. For3rd year, based on broadband polarization-dependent metasurfaces, amulti-function spectrometer will be demonstrated for measuring thematerials with birefringence, chirality, dichroism and circulardichroism.
