Abstract
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.
