活动主题：maxwell’s fish-eye lens and its applications
形式：线上学术报告
活动内容摘要：
maxwell's fish-eye lens is a special lens that can focus any point source perfectly. such a lens is also called an absolute instrument, and has been widely used to design invisibility cloaks. in this talk, i will share our recent works along this line, both theoretically and experimentally. it includes self-focusing and talbot effect, waveguide crossing, conformal caustics and singularities, and geodesic lenses.
