Engineering scattering patterns with asymmetric dielectric nanorods

Isro, Suhandoko; Iskandar, Alexander; Kivshar, Yuri; Shadrivov, Ilya


By controlling interference of Mie resonance modes of various nanostructures, we can achieve a large number of nontrivial effects in nanophotonics. In this work, we propose a cylindrical structure in which the spectral overlap of the Mie-type modes can be controlled by drilling a hole parallel to the axis, thus changing unidirectional scattering. We further demonstrate that the scattering patterns can be tailored by rotating the structure to achieve almost arbitrary scattered wave direction.
