Abstract

An analytical model to the modal characteristics of Metal-Insulator-Metal (MIM) plasmonic waveguide is proposed. An expression to the propagation constant and losses as function in the refractive index, the waveguide width, and the wavelength is obtained and verified using finite difference based mode-solver. These expressions are used to develop a theoretical model to the behavior of a plasmonic nano-filter based MIM configuration. The proposed model shows a good agreement with FDTD simulations. Using this model, the sensitivity of the filter to different design parameters is investigated and analyzed analytically. Therefore, the optimum values of different design parameters can be obtained analytically. By using this theoretical model, a sharp resonance filter with narrow bandwidth, compact size, low loss, and good sensing characteristics can be demonstrated. The proposed filter can be used in different applications such as, biological sensing and communication systems.
