On computational methods in photonic crystal finite difference time domain method ( fdtd ) and plane wave expansion method ( pwe ) are widely used in calculation the dispersion relation of the photonic crystals
光子晶体计算方法的研究用于计算光子晶体的计算方法中，有限时域差分方法( fdtd )和平面波展开方法被广泛使用，我对这两种方法都有所研究，也有所突破创新。
I carried my research on both the two computation methods and fruitful results were obtained . for the fdtd method , i solved the instability problem of the method in the non - orthogonal coordinate system . for the pwe method , i introduce the linear transform in to calculate analytically the fourier coefficients of complicated photonic crystals
对于有限时域差分方法，我解决了一个影响这种方法在斜坐标使用的稳定性问题，得到了传统的yee型差分在斜坐标里的扩充；对于平面波展开方法，我引入了线性变化求富里叶展开的系数，这种方法的好处可以很方便快捷的获得复杂光子晶体的富里叶系数。
