基于平面波展开法,分析聚苯乙烯三维光子晶体的能带结构和传输特性.研究聚苯乙烯三维光子晶体对压力的响应性质;计算结果表明：0-41.3 MPa的外加压力与归一化频率0.596-0.608之间具有良好的线性关系,通过测量归一化频率可以感知压力的大小;由于光子晶体的结构周期与光波长为一个数量级,也就有可能制造出一系列精巧的三维光子晶体压力传感器.

英文摘要：

Band structure and characteristics of polystyi＇ene three-dimensional photonic crystals are analysed with a plane-wave method. Effects of pressure on polystyrene three-dimensional photonic crystals are studied. Linear relation between pressure ranging from 0 to 41.3 MPa and normalised frequency ranging from 0.596 to 0.608 nm is shown. Since structure scale of photonic crystal is close to the wave-length, it is possible to realize three-dimensional photonic crystal pressure sensors with high accuracy.
