electron metal (比鋁輕的)鎂合金。

electron microscope

In this thesis , a new finite difference time domain ( fdtd ) method is developed to treat a two - dimensional photonic crystal consisting of nearly - free - electron metals . the method is used to calculate the band structures and investigate defect modes and guide modes in such a photonic crystal 本論文首先發展了一種基于等離子模型的有限差分計算方法,并應用于二維金屬光子晶體,有效地計算了該類光子晶體的能帶結構。
