▲ [5p-A410-2] Optical Anapole Mode with Planar Metamaterials
キーワード:Metamaterials, Toroidal, Anapole
A novel three-dimensional plasmonic metamaterial which is able to generate a transverse toroidal dipole moment under normal illumination is presented in the optical region. In addition to the toroidal dipolar response, a non-radiating anapole mode resulting from the destructive interference between toroidal and electric dipoles is also observed. Different from the previous works, it is a real artificially designed and fabricated plasmonic metamaterials for the generation of both transverse toroidal dipole moments and associated anapole mode, and readily available for feasible applications.
