Propagation of electromagnetic waves in an inhomogeneous nonlinear medium

Propagation of TE-mode waves along a spatially inhomogeneous layer of a self-focusing or self-defocusing medium is investigated. it is found that under certain conditions, depending on the electromagnetic field strength, waveguide propagation of the TE field may be disrupted. Conditions for localization of a strong field in the plasma-layer region leading to oscillations of a weak field at infinity are elucidated for TE waves propagating along an inhomogeneous plasma layer.
