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
光子晶體計算方法的研究用於計算光子晶體的計算方法中，有限時域差分方法（ fdtd ）和平面波展開方法被廣泛使用，我對這兩種方法都有所研究，也有所突破創新。 -
In and around the town are 175 hectare botanical garden, pwe kauk and a ni - sakhan waterfalls, gokhteik viaduct and peik chin myaung caves limestone caves
市裡和周邊分佈著一百七十五公頃的植物園，比考大瀑布和阿尼斯堪大瀑布，固泰橋和倍欽苗溶洞（石灰巖溶洞） 。 -
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
對于有限時域差分方法，我解決了一個影響這種方法在斜坐標使用的穩定性問題，得到了傳統的yee型差分在斜坐標里的擴充；對于平面波展開方法，我引入了線性變化求富里葉展開的系數，這種方法的好處可以很方便快捷的獲得復雜光子晶體的富里葉系數。
