The characteristics of nickel-based elliptical cylinder plasmonic nano-waveguides in the near-infrared wavelength

In this article, a nickel-based elliptical cylinder plasmonic Nano-waveguide (NECPNW), layers is used to serve the coating purpose. The results of this purposed structure that are yielded by Finite Element Method in the COMSOL-multi-physics simulator program reflect that this approach has the capacity for more field confinement and simultaneously less dissipation. As a result, surface plasmons (SPs) can be utilized to improve data exchange. Our resulting has displayed that the proposed waveguide has a figure of merit over ۳۵۰۰۰, propagation length over ۴۷۰ μm, and a normalized mode area of ∼〖۱۰〗^(-۳) by tuning the semi-major axis Ni nanowire, wavelength of incident light, and the thickness of the dielectric layers. Hence, proposed waveguide shows longer propagation length and better figure of merit than the similar plasmonic waveguides.
