Abstract:	本計劃擬發展基於表面電漿子共振及幾何相位調變的超穎光學系統。過往研究者利用超穎材料/超潁介面展現了各種具特異光學性質的超穎元件，本計劃將嘗試將超穎元件與光學系統整合為超穎光學系統。本計劃為三年計劃，計劃第一年我們將在微波波段設計製作具有2pi相位調變能力的寬頻超潁介面晶胞作為計劃第二及第三年的先導研究，本年度我們將完成微波波段超潁介面的遠場相位及光譜特性量測，近場侷域電磁波特性量測。計劃第二年我們將利用寬頻極化無關的2pi相位超潁介面製作一個可見光波段的超潁介面，並利用其消除光學系統相差，並評估該光學系統的光學品質。計劃第三年我們將利用寬頻極化相關的2pi相位超潁介面設計製作一個能夠量測雙折射、手鏡、二色性、圓二色性等特性的多能光譜系統，並評估此超穎光學系統之量測極限。 ;The aim of this project is to develop a meta-optic system based plasmonics and geometry phase. It has been demonstrate versatile meta-devices with extraordinary optical properties based on metamaterials/metasurfaces. In this project, we are going to integrate meta-devices with traditional optical system to be a meta-optic system. This project is a three years one. For 1st year, a broadband metasurface with 2p phase modulation in microwave regime will be designed, fabricated and measured. We will setup a microwave measurement system for measuring the far-field / near-field properties of metasurfaces. Transmission/reflection spectrum, phase modulation, and localized field of the microwave metasurface will be measured. For 2nd year, a broadband polarization-independent meta-corrector in visible range will be demonstrated for eliminating the aberrations of an optical system. The optical performance of the optical system will be evaluated as well. For 3rd year, based on broadband polarization-dependent metasurfaces, a multi-function spectrometer will be demonstrated for measuring the materials with birefringence, chirality, dichroism and circular dichroism.
