Abstract:Optical cages have recently received extensive research and attention due to their potential applications in optical cloaking, microscopic imaging, and trapping particles or atoms. However, the creation of a controllable spatial multi-optical cage array with tunable dark regions comes to a great challenge, which limits the effectiveness of the above applications. To this end, we analyze the radiation pattern of a reverse-focused magneto-electric dipole antenna in a 4Pi optical focusing system. It is found that… Show more
