The dispersion relation for surface plasmon at a metal-Kerr nonlinear medium interface
|
Abstract:
The dispersion relation of transverse magnetic (TM) wave and transverse electric (TE) wave for surface plasmon at a metal-Kerr nonlinear medium interface are analyzed based on the Maxwell equations and the boundary conditions.The dispersion relation of TM wave is complex, due to the nonlinearity, and it has a dielectric coefficient and intensity-dependent expression.However, the TE wave does not exist at this interface as in the linear case.
