We present a theoretical analysis for the Goos-Hänchen and Imbert-Fedorov shifts experienced by an X-wave upon reflection from a dielectric interface. We show that the temporal chirp, as well as the bandwidth of the X-wave, directly affect the spatial shifts in a way that can be experimentally observed, while the angular shifts do not depend on the spectral features of the X-wave. A dependence of the spatial shifts on the spatial structure of the X-wave is also discussed.
我们对X波在电介质界面反射时所经历的古斯-汉欣位移和因伯特-费多罗夫位移进行了理论分析。我们表明,时间啁啾以及X波的带宽,会以一种可通过实验观测到的方式直接影响空间位移,而角位移并不依赖于X波的光谱特征。我们还讨论了空间位移对X波空间结构的依赖性。
