【内容摘要】：This presentation describes studies of optical phenomena at the nanoscale for coupling light into high intensity ,nanometer scale spots. 
 
In particular, I will describe aperture-type optical antennas with specially designed geometry. These antennas are designed to strongly  resonate with the coming radiation, and the radiation intensity is further increased using various strategies to enhance resonances, or arranging an array of such structures that are strongly coupled through both electric and magnetic fields. It will be demonstrated that these special nanoscale optical structures can be used for a wide range of engineering applications, including high precision optical nano manufacturing ,improving efficiency of solar energy harvesting ,ultra-high density, next generation data storage called Heat Assisted Magnetic Recording, and achieving special selective radiation surfaces for both near-field and far-field radiation. In addition, I will introduce the state-of-the-art facilities at the Center for Micro and Nanoscale Research and Fabrication, USTC for conducting researches in the areas mentioned above.
