temperature effect on the goos-hanchen effect in the nonlinear nanocomposites

In this work, temperature effect on the goos-hanchen (gh) shift in the metal-dielectric nanocomposites consist of the ellipsoidal metal nanoparticles and the ellipsoidal dielectric nanoparticles are investigated the effective medium approximation in the quasi-static regime to calculate the e. we used ffective permittivity of a composite ( ) and the stationary phase method is utilized to investigate the gh shifts. spectral representation theory has been used to obtain the local electric field in the nonlinear metal nanoparticles. our numerical analysis revealed that in addition to the magnitude of the gh shift, the lower and upper threshold of the gh bistability as a nonlinear response will be affected by a temperature increment.
