平面波展开 meaning in Chinese
plane wave expansion
Examples
- Two - dimensional acrylic / air sonic band structure with square lattice is considered in the numerical example
本文以平面波展开法分析压克力?空气声子晶体声波全频沟之现象。 - The plane expansion method is widely used in the analysis for the band structures of photonic crystals
平面波展开方法在计算光子晶体能带方面应用广泛，但是用于分析光在光子晶体中的行为却不方便。 - But it is very inconvenient for the analysis of light ' s behavior in it . in this thesis , a new method based on plane expansion method is proposed
本文在深入分析平面波展开方法的基础上，对这种方法进行了修正，使得它适合于分析光子晶体中光的传播性质。 - Using the plane wave expansion method , from the computation result for the band gaps structure of infinitd periodic one dimension phononic crystal , it is found the width of the first gap relates with the material portion ratio
利用平面波展开法，计算一维无限周期结构声子晶体的带隙结构，发现每一带隙的宽度与材料的组份比有关。 - In the present thesis , we have considered a 2d photonic crystal of square lattice formed by two materials of dielectric constants . we consider the structure to be formed by a large number of small rectangle or square pixels of uniform size
本文提出不管哪种结构均可看成是由很多个同样大小的小矩形或正方介质像素组成的，对这种二维像素型光子晶体结构，对传统平面波展开法可经修正使之收敛速度大大提高。
