Abstract
A spherical designer electromagnetic surface plasmon open resonator is provided. The open resonator includes a resonator inner core and a resonator outer shell. The resonator inner core is located in an inner center of the resonator outer shell, and the resonator inner core and the resonator outer shell are coaxial. The disclosure provides a device that implements the superscattering function for incident waves in all incident directions and in all polarization directions, and a spherical open resonator is implemented. The scattering cross section of the disclosure can be more than five times greater than that of a metal sphere of the same size, and the operating frequency can be flexibly designed. By utilizing the characteristic that the scattering cross section of the spherical designer electromagnetic surface plasmon resonator is much greater than its own geometric cross section, the electromagnetic super-scattering device can be implemented.
