TI  - Dispersion Relation for 2D Transverse Magnetic (TM) Plasmonic Wave: Analytic Versus FEM
JO  - Japan Journal of Research

IS  - 1
AB  - A metal-dielectric interface has been studied in this paper in the light of wave propagation characteristics.
A new analytical result, through a simpler approach for deriving the dispersion equation in plasmonic
waveguides, has been reported and visualized. A two-dimensional Transverse Magnetic (TM) wave is
theorized and analyzed with respect to its propagation along the boundary of metal and air. Mathematical
analysis results in the relationship between the propagation parameter and wavelength of operation. The
plots reveal good conformity with the previous studies. For comparison, the propagation characteristics
in free space have also been included. To validate the proposed results of this study, Finite Element
Analysis (FEA) has been used to visualize the distribution of fields near the metal-dielectric boundary.
