title: Impedance calculation and equivalent circuits for metal-insulator-metal plasmonic waveguide geometries.
abstract: This Letter presents an analytical expression for the equivalent impedance of the fundamental mode of both 2D and 3D metal-insulator-metal (MIM) plasmonic waveguides. It also presents circuit models for passive 2D MIM waveguide components represented by additional parasitic circuit elements. Moreover, a modeling library for various 2D MIM waveguide structures is developed. The proposed analytical results have been verified and show great accuracy compared to the full-wave characterizations.
