Planewave has the overall direction, compared with the normal migration, the plane-wave imaging results can be comparable to, and has a high computational efficiency.
We have investigated the guide modes in two kinds of two_dimensional photonic crystal heterostructures by using the planewave expansion method combined with the supercell technique.
利用平面波展开方法与超原胞方法研究了两种不同晶格的光子晶体异质结的界面态。
