High-contrast and reversible scattering switching via hybrid metal-dielectric metasurfaces

Ward, Jonathan; Zangeneh Kamali, Khosro; Xu, Lei; Zhang, Guoquan; Miroshnichenko, Andrey; Rahmani, Mohsen

Description

Novel types of optical hybrid metasurfaces consist of metallic and dielectric elements are designed and proposed for controlling the interference between magnetic and electric modes of the system, in a reversible manner. By employing the thermo-optical effect of silicon and gold nanoantennas we demonstrate an active control on the excitation and interference between electric and magnetic modes, and subsequently, the Kerker condition, as a directive radiation pattern with zero backscattering,...[Show more]
