实验表明，角古斯-汉臣（GH）效应可以很容易地观察到，也没有采用它的共振增强在布鲁斯特入射。一个s偏振光束被用来从光束的传播动力学解耦的偏振。我们发现，在这种情况下，角GH效应可以强烈增强通过增加高斯光束的角孔径。我们的实验提出了一种观察角GH效应的真正的标量波，如声波和量子物质波的路线。(C)2010年美国光学学会
We show experimentally that the angular Goos-Hanchen (GH) effect can be easily observed, also without employing its resonant enhancement at Brewster incidence. An s-polarized beam was used to decouple the polarization from the propagation dynamics of the beam. We found that, in this case, the angular GH effect can be strongly enhanced by increasing the angular aperture of the Gaussian beam. Our experiments suggest a route toward observing the angular GH effect for true scalar waves, such as acoustic waves and quantum matter waves. (C) 2010 Optical Society of America
