The mode properties of symmetric and non-symmetric one-dimensional photonic crystals with a sandwich layer defect were investigated by using the optical transmission matrix method.
利用光学传输矩阵方法研究对称和非对称一维缺陷光子晶体的缺陷模式特性。

Elements by the highly-accuracy six-node triangular element are divided. Stiffness matrix and mass matrix of sandwich panel are established and then deduced dynamical equations of finite elements.
By studying the application of sandwich-structured synthetic diamond core bits, following results are concluded: Matrix hardness can be HRC3-5 higher than that of similar ordinary ones;
