【摘要】 本文导出了从吸收媒质上反射的s和p两种偏振的Goos-Hnchen位移的一般表达式。若令消光系数等于零,它们就简化成McGuilk和Carniglia给出的仅用于非吸收媒质的公式。吸收媒质的位移,在任何不为零的入射角度时都有。在镓的表面上,位移有几个波长。更多还原

【Abstract】 General expressions of Goos-Hanchen shift for both s and p polarizations from absorbing medium has been derived in this paper. Let the extinction coefficient be equal to zero, they will be simplified to the formulae[1] given by M. McGuirk and C. K. Carniglia, which are only fit for non-absorbing medium. The shift from absorbing medium occurs at any incident angle except zero angle. On Gallium surface, Goos-Hanchen shift may have several wavelengths.更多还原
