Tightly confined plasmon waveguide modes supported by semicircular cross section top silver nanoridges are investigated. Mode field profiles, dispersion curves, propagation distances, confinement factors, and figures-of-merit of the semicircular top silver nanoridge plasmon waveguide mode are calculated for different radii of curvature at different wavelengths. It is found that semicircular top silver nanoridges support tightly confined quasi-transverse electromagnetic (TEM) and quasi…
