A transmission type plasmonic multilayer filter is theoretically investigated using three-dimensional rigorous coupled wave analysis (RCWA) method. The design rule of the resonance properties associated with the weakly localized surface plasmon modes in metal/insulator/metal waveguide arrays is discussed. The optical performances with respect to the geometrical parameters of the plasmonic structure are evaluated. Through manipulating the geometric parameters of the metal/insulator/metal waveguide, the optical properties of the filter can be engineered.
