Rigorous envelope approximation for interface wave-packets in Maxwell's equations in 2D localization
We study transverse magnetic (vector valued) wave-packets in the time dependent Kerr nonlinear Maxwell's equations at the interface of two inhomogeneous dielectrics with an instantaneous material response. The resulting model is quasilinear. The problem is solved on each side of the interface and the fields are coupled via natural interface conditions. The wave-packet is localized at the interface and propagates in the tangential direction. For a slowly modulated envelope approximation thedoi:10.5445/ir/1000147888 fatcat:3253ni7mfzcevnq2qbnoeo4nvm
