Metasurfaces are arrays of subwavelength anisotropic light scatters (optical antennas) that can produce abrupt changes in the phase, amplitude, or polarization of light. Within last few years significant progress, design of metasurfaces that refract and focus light, enabling many unique properties and applications such as ultrathin focusing lens, advanced imaging system, holograms, optical vortex generation/detection, perfect absorber/color filter, etc.
This seminar will cover the fundamental principles and technological applications of metasurfaces, and particularly aim to explore on new structures, materials, and advanced optical science/functionality of metasurfaces for applications spanning from imaging system, laser development, bio/chemical sensing, energy harvesting devices, quantum/communication system, and data storage.
