Study of reflection/transmission behavior of a planar nonlinear dielectric–NID interface

Abstract The manuscript is devoted to study the behavior of reflection and transmission from a planar interface of second order nonlinear–linear NID medium. Slowly varying amplitude approximation is used to simplify the solution of nonlinear wave equation. Analysis is conducted by considering imperfect matching case of permittivity for the nonlinear medium. It is noted that behavior of the reflection coefficient changes drastically when the angle of reflection for nonlinear polarization becomes complex. It is also observed that dimension of the NID medium is an effective parameter to control the behavior of coefficients.
