Abstract

In recent years, the fantastic phenomena of negative Goos-H\"anchen shifts were studied in several optics experiments with the positive refractivity materials, which is predicted by many scientists through both classical physics or quantum physics theory. In order to verify the negative Goos-H\"anchen shifts phenomena, an experiment in microwave frequency was done with nano-metal-films on prism surface. Because using nano-metal-films enhances self-interference effect, not only were the negative Goos-H\"anchen shifts obtained, but also the giant Goos-H\"anchen shifts was appeared.
