Abstract

In this article, the reflection properties of the plane wave incident at isotropic fractal dielectric-anisotropic chiral interface have been demonstrated. The properties of the reflected wave have been discussed explicitly as a function of field parameter $\mathrm{\Omega }=\{{\theta }_i,\underline{\underline{\epsilon }},\kappa ,\zeta \}$. The Goos H$\ddot{a}$nchen Shift in the reflected wave from the said interface has also been predicted based on the stationary phase method. Furthermore, for the sake of tuning the Goos H$\ddot{a}$nchen Shift, the impact of field parameter $\mathrm{\Omega }$ has also been scrutinized and agreement with the results already presented in literature has been obtained..
