While smooth surfaces send back a reversed, right-polarizedwave, rough areas return left-polarized waves.
光滑表面会反射一个反向的优选极化波,而粗糙地区的反射波是左旋极化波。

It is find that there isn't any absolute PBG in any condition, but big tuning range of te polarizedwave can be achieved by changing the index of liquid crystal.
发现均无完全光子禁带出现,而通过改变液晶折射率可得到大调谐范围的TE偏振光。

So, the scattered electromagnetic wave is no longer a completely polarizedwave, but a partially polarizedwave, although the incident wave is completely polarized.
