真空中光的引力辅助负光的折射
Towards gravitationally assisted negative refraction of light by vacuum
摘要：
在有限的时空范围内，电磁平面波在受引力影响的真空中的某些方向上的传播可以是这样的，即相速度矢量在时间平均的坡印廷矢量上投影为负。这一结论表明，除其他外，真空的引力辅助负折射。
英文摘要：
Propagation of electromagnetic plane waves in some directions in gravitationally affected vacuum over limited ranges of spacetime can be such that the phase velocity vector casts a negative projection on the time-averaged Poynting vector. This conclusion suggests, inter alia, gravitationally assisted negative refraction by vacuum.
