Abstract

Due to all dielectric nanodisks with high refractive index material supporting simultaneously electric and magnetic resonances, unusual properties including entirely forward and backward scattering can be reached by properly design. Here, we show that azimuthally symmetric unidirectional scattering can be achieved by the interference effect of electromagnetic resonances in nanodisks. It is found that unidirectional scattering with small main lobe beamwidth and large magnitude can be further enhanced by a nanoparticle chain. In addition, the dielectric environment, gap distance between nanodisks, and the number of nanodisks in chain are detail analyzed in unidirectional scattering. Our results can be useful in fields of nanoantennas, nanoscale lasers, and photovoltaic elements that need the suppression of backward scattering.
