Abstract: | We study the transmission property and field distribution in metal-dielectric multilayer structure. It is shown that the thickness of dielectric strongly affects the transmission spectral behavior and the electric field distribution inside the structure. With increase of the dielectric thickness we can get multi-passband in the spectrum over a tunable range of frequencies from ultraviolet to infrared frequency range. Moreover, the field distribution under all resonant wavelengths is obtained, which presents a law of correspondence with the transmission spectrum of the structure and a new phenomenon that multi-node appears in the field distribution in each metal-dielectric-metal cavity is predicted. |
