摘要
从光的电磁理论出发,导出了光在单负材料周期性结构的传输矩阵。利用光学传输矩阵法对由两类单负材料组成的一维光子晶体的光学传输特性进行了数值模拟和理论分析。结果表明,这种结构具有一类新型的光子带隙。与布喇格带隙不同的是,这类光子带隙不会随着晶格常数的缩放而移动。
Based on electromagnetic theories, the expression of transfer matrix of periodical structure formed by single-negative materials is deduced. By using such transfer matrix, the numerical simulation and analyses for the properties of light propagation in one-dimensional photonic crystals constructed by two kinds of single-negative materials have been made. It's shown that this structure can possess a new type of photonic gap. Distincted from the Bragg gap, the photonic gap is invariant with scaling length.
