摘要
用时域有限差分方法计算了一组具有相似几何结构且包含理想金属材料的准分形光子晶体的能带 .数值计算结果表明 ,这种准分形结构光子晶体具有绝对带隙 ,且带隙的宽度会随着分形级数的增大而增大 .同时 ,随着级数的增大 ,其能带在整体地趋向于高频端的同时 。
The photonic band of a set of quasi_fractal photonic crystals, which have similar structure and include idealized metal, is computed by finite_difference time_domain method. The result shows that there are photonic band gaps in this kinds of quasi_fractal photonic crystals. It is found that, with increasing fractal series, the width of the photonic band gap is enlarged, the frequency of the photonic band totally trends to high frequency quickly, at the same time, the photonic band is quickly hauled to line and become a energy level.
