Goos–Hanchen Shift in the presence of dispersive dielectric–magnetic medium using Lorentz–Drude Model

The purpose of this manuscript is to quantitatively analyze the reflection coefficient and Goos–Hanchen Shift (GHS) owing to a planar interface of a dispersive dissipative dielectric–magnetic metamaterial for parallel/ perpendicular polarization. To achieve the goal, Lorentz–Drude Model is utilized to introduce a lossy/ lossless dispersive dielectric–magnetic metamaterial medium. As the medium on one side of the interface is dispersive, so it behaves as Double-Positive/Double-Negative/Epsilon-Negative/Mu-Negative metamaterial, depending on the value of operating frequency. The behavior of reflection coefficient, its phase and GHS for these medium has been studied. It has been noted that the GHS can be effectively managed by introducing the losses appropriately.
