揭示了极端光学各向异性介质板内倏逝波空间谐波的显著增强。这种现象是驻波泵送的结果，具有对材料损耗弱敏感的特点。这样的特性可以使得能够在远离对象的相当大的距离处进行亚波长成像。
Significant enhancement of evanescent spatial harmonics inside the slabs of media with extreme optical anisotropy is revealed. This phenomenon results from the pumping of standing waves and has the feature of being weakly sensitive to the material losses. Such characteristics may enable subwavelength imaging at considerable distances away from the objects.
