Impedance Matching Induce High Transmission and Flat Response Band-Pass Plasmonic Waveguides

XU, Yi; Miroshnichenko, Andrey; Lan, Sheng; Guo, Qi; Wu, Li-Jun


We consider a model utilizing the concept of impedance matching, which can be applied to design the coupled cascaded plasmonic cavity waveguide with desired properties. We use a transfer matrix method to obtain its transmission and dispersion diagrams. Base on this method, we demonstrate that a band-pass metal-dielectric-metal plasmonic filter with quasi-flat group velocity and tunable bandwidth can be achieved.
