چکیده
|
an arrayed structure of asymmetric multilayered ultra-thin metal stripes is proposed to achieve a narrow transmission peak in an ultra-broad transmission valley, which is formed due to the destructive multiple-interference tunneling existed in an ultra-thin metal and dielectric multilayers. the transmission peak is influenced by two resonant modes. one is the coupled gap surface plasmon (cg-sp) resonance mode confined in entire multilayered ridges, the other is the modified gap surface plasmon (g-sp) mode within metal-dielectric layers. furthermore, the transmission mode and the stopband are tunable in a wide range through designing the dimension parameters. the proposed plasmonic structure is promising for wideband filters.
