Abstract

Direct interference between the induced magnetic and electric moments in a hybrid metal-dielectric nanodisk is demonstrated for the realization of unidirectional forward scattering in the near-infrared region. Specifically, the unidirectional forward scattering with high efficiency of the designed nanoantennas is not limited to one specific wavelength but can fit multiwavelengths. The scattering properties of the metal-dielectric hybrid nanodisk at a specific wavelength can be adjusted to meet the Kerker's type condition. In addition, the simulated optical properties of the nanoantennas reveal that the nanodisk arranged in an array exhibits efficient absorption leading to enhanced directionality. Our results provide insights into the design and engineering of highly directive nanoantennas.
