摘要
用平面波展开法研究了二维圆柱形光子晶体的完全禁带与填充比、介电常数比之间的关系.研究发现,并非介电常数比越大,完全禁带宽度就越大,而是有一个峰值.
Plane wave expansion method was employed to study the relation between the bandgap of two-dimensional columnar photonic crystals and the filling ratio and dielectric constant ratio. It is shown that the complete bandgap does not increase monatonically with the dielectric constant ratio, but has a peak value instead.
