Wiegrefe、Fedorov、Costa de Beauregard和Schilling讨论了椭圆偏振光全反射中存在的横向能量通量，后两人提出了反射光束横向位移的公式。我们用类似于Kristoffel和Renard对Goos-Hänchen纵向位移的推导的能量-通量守恒的论点计算了横向位移，从而得到了一个不同于先前作者的公式。我们还通过实验测试了横移的存在，在圆偏振和准极限全反射的最佳情况下，通过使用两种略有不同的乘法程序。我们的测量结果完全证明了我们的横向位移公式与Costa de Beauregard和Schilling的公式是正确的。我们的结果与消失波内自旋光子的速度和动量的非共线性的相关性进行了简要的讨论。
Wiegrefe, Fedorov, Costa de Beauregard, and Schilling have discussed the transverse energy flux existing in total reflection of an elliptically polarized light beam, the latter two proposing formulas for the transverse shift of the reflected beam. We have calculated the transverse shift by an energy-flux-conservation argument similar to Kristoffel's and to Renard's in their deduction of the longitudinal Goos-Hänchen shift, thus obtaining a formula different from those of the previous authors. We have also tested experimentally the existence of the transverse shift, in the optimal case of circular polarization and quasilimit total reflection, by using two slightly different multiplying procedures. Our measurements definitely vindicate our own formula for the transverse shift against both Costa de Beauregard's and Schilling's. The relevance of our results in connection with noncollinearity of velocity and momentum of the spinning photon inside the evanescent wave is very briefly discussed.
