Abstract.   Asymptotic calculation of electromagnetic field of a plane wave reflected by a stratified dielectric medium with continuous dependence of dielectric permeability on the depth is carried out. Formulas for module of the reflection coefficient are derived with the use of the phase integral method.
Keywords: high-frequency asymptotics, reflection coefficient, phase integral method.
