【摘要】 运用特征矩阵法研究了介电常数受任意函数调制的一维光子晶体中光的传播特性,发现一维光子晶体的介电常数只要满足周期性分布,就会具有与一般光子晶体相似的带隙结构.还更具有一般性地研究了介电常数受随机函数周期调制时的光子晶体的带隙结构及其特点,从而为灵活实现某特定带隙的晶体提供了新的方法.更多还原

【Abstract】 We studied the light propagation in one-dimension photonic crystal made of media whose dielectric constant modulated by a function from eigen matrix method and found that as long as the dielectric constant changes periodically,the media has the similar band gaps as general photonic crystal.More generally,we studied the band gaps of the photonic crystal with dielectric constant modulated by random function,and a new method for getting a special kind of band gaps was provided.更多还原
