Abstract

Strong resonant light scattering by an Au–Si sliced nanorod is investigated by the finite element method (FEM) based on COMSOL Multiphysics. Stemming from the interference between the electric, magnetic and toroidal multimodes in Au–Si sliced nanorod, the forward scattering is enhanced and backward scattering is attenuated substantially in visible region. Moreover, the high-efficiency unidirectional forward scattering is not limited to one specific wavelength but can fit in the multiple wavelengths. The structural parameters have an effect on the enhancement of different multimode resonances.
