1) anomalous refraction
反常折射
2) Abnormal Refraction
反常折射
1.
It shows that,for the one-dimensional photonic crystals,there are abnormal refraction in the first band.
结果表明,对于一维光子晶体,在第一能带内,存在反常折射现象。
3) anomalous refraction
反常(大气)折射
5) unusual refraction
异常折射
1.
Atmosphere absorbs the electromagnetic wave so that the radar detection distance be reduced, and the atmospheric unusual refraction changes the radar detection distance too.
大气环境对电磁波的吸收衰减作用使雷达的作用距离减小,大气异常折射现象使雷达的作用距离增大或减小。
6) refraction constant
折射常数
