To date the experimental reports on Goos-Hanchen (GH) shift of left-handed metamaterials (LHMs) have not been reported since it is theoretically demonstrated. The GH shift of LHMs based on the silver dendritic structure via interferometry is experimentally mecisuked. Wollaston prism is utilized to divide the incident light into s polarized and p polarized light. Then the two polarized light beams are made to interfere with each other to obtain the interference pattern after being reflected from the surface of the sample. And the value of GH shift is obtained by analyzing and calculating the interference pattern. Experimental results confirm that GH shift is negative as the frequency of incident light is consistent with the resonant frequency of silver dendritic LHMs.
