Abstract

In this work, an observation of Goos–Hänchen shift in the terahertz range on a metal surface with a change in temperature is reported. A s-polarized terahertz wave incident at 45° onto an aluminum surface produces a positive GH shift that increases with temperature. We used an interference method by observing the change of interference fringes of two THz beams to verify the existence of the GH shift and indirectly measured the quantity of it. Based on experimental data and theoretical analysis, the increase of GH shift on the aluminum surface as a function of temperature between 23 °C and 101 °C has been obtained. Considering the effect of the thermal expansion, the maximum variation of GH shift is 267.2 μm with the temperature changing 78 °C.
