Abstract

We propose a scheme to manipulate the Goos-Hänchen shift of a terahertz wave reflected from the prism/magnetic dielectric. By adjusting the external applied magnetic field, the refractive index of the magnetic dielectric can be changed, so the Goos-Hänchen lateral shift is dynamically tuned. Numerical calculation results further indicate that the proposed configuration has the potential application for the integrated terahertz wave switch with the extinction ratio of 18.5dB at terahertz wave wireless communication frequency of 0.857THz.
