Novel optical transmission property of metal–dielectric multilayered structure

摘要

A kind of planar metal–dielectric multilayered plasmonic structure has been proposed and its optical properties have been studied. Numerical calculations show that both the electric resonance (surface-plasmon polariton resonance) and the magnetic resonance (localized magnetic-plasmon resonance) can enhance the optical transmission. Moreover, by modulating the dimensions of the proposed structure, a large resonance quality factor and a continuum resonance can be achieved. These controllable optical properties might be useful for various practical implementations.
