- Title
Dispersion and Field Distribution of SPP Waves at the Interface of a Metal and Nonlinear Magnetic Material.
- Authors
R, Ajith; Mathew, Vincent
- Abstract
We study the properties of surface plasmon polaritons at an interface between a metal and a strongly nonlinear magnetic cladding, characterized by permeability $\mu=\mu_\textrm{l}+\mu_{\textrm{nl}} H^2$. It is observed that the dispersion of modes has a significant dependance on the incident power. The incident power can be adjusted to control the propagation length. In addition, the structure shows strong confinement of the modes at the interface.
