摘要:

本文用二维空间扫描方法直接研究了微波频率电磁辐射的(1+1)维横向局域化。由于纵向方向可以映射到时间上,我们的实验提供了独特的快照建立本地化波。波函数的演变与数值计算进行了比较。耗散被证明对横向本地化的发生没有影响。在空间中观察到的波函数的振荡,并解释了本征态之间的拍频。

英文摘要:

We study (1+1)D transverse localization of electromagnetic radiation at microwave frequencies directly by two-dimensional spatial scans. Since the longitudinal direction can be mapped onto time, our experiments provide unique snapshots of the build-up of localized waves. The evolution of the wave functions is compared with numerical calculations. Dissipation is shown to have no effect on the occurrence of transverse localization. Oscillations of the wave functions are observed in space and explained in terms of a beating between the eigenstates.
