Based on this method , the wavevector diagram for photonic crystals can be easily obtained 基于这种修正,可以容易地得到光子晶体中的波向量图。
By using this diagram , the behavior of light in photonic crystals can be analyzed qualitatively 根据波向量图可以定性分析光在光子晶体中的行为。
Based on the wavevector diagram and group velocity , the property of light in photonic crystals can be analyzed quantitatively 基于波向量图和群速度,可以很好地分析光在光子晶体中的行为。
While the new components having the same numbers with these original physical vectors are introduced and the new components are combined with those original physical components to form a new symplectic space , the ray problem of wave propagation in geometrical optics is converted into the problem of lagrange submanifold in the symplectic space 通过引入波向量(慢度向量) ,将物理空间中几何光学的射线问题转化为辛空间中的lagrange子流形(超曲面)问题。
