我们研究了电磁波在三维无序光子晶体中的传输，这些光子晶体平均具有周期性，具有菱形对称性。用传递矩阵法计算了透射率。我们研究了两种不同的几何形状的散射体：球和棒连接最近的邻居。我们发现，间隙的周期性结构的生存到一个更高的量的无序在棒的情况下比在球的情况下。我们认为，这是由于存在任何数量的无序的杆结构的连接。@S0163-1829~99！04120-X编号
We study the transmission of electromagnetic waves propagating in three-dimensional disordered photonic crystals that are periodic on the average with a diamond symmetry. The transmission has been calculated using the transfer matrix method. We study two different geometries for the scatterers: spheres and rods connecting nearest neighbors. We find that the gaps of the periodic structure survive to a higher amount of disorder in the rods’ case than in the spheres’ case. We argue that this is due to the connectivity of the rod structure that exists for any amount of disorder. @S0163-1829~99!04120-X#
