Modal Characteristics of Plasmonic Transmission Lines in Multi-Layered Media using the Method of Moments

摘要

This paper presents an integral equation formulation used to obtain the mode characteristics of plasmonic transmission lines. These lines can have any topology and are generally located in multi-layered structure of metallic or dielectric layers. The developed solver calculates the attenuation and phase constants of the lines using the method of moments technique which is characterized by its accuracy and high speed compared to other numerical techniques. The solver also calculates the current components inside the metallic strips constructing the transmission lines. The solver is examined on a number of transmission lines to ensure its accuracy. The obtained results agree very well with the commercial software CST.
