Researches on far-field super-resolution imaging based on time-reversed electromagnetics at UESTC

Time reversal (TR) of electromagnetic waves exhibits temporal and spatial focusing. With the assistance of near-field sub-wavelength structures, TR electromagnetic waves can show spatial super-resolution focusing both in the near- and far-fields. Based on this characteristic, TR technique has found potential applications in super-resolution imaging. This invited talk simply gives an overview on far-field super-resolution imaging based on TR technique at University of Electronic Science and Technology of China (UESTC) in recent years.
