| 摘 要： | 应用多光子非线性康普顿(Compton)散射模型和有限时域差分法,研究了多光子非线性Compton散射对非磁化等离子体光子晶体光子禁带密度和温度特性的影响,提出了将入射光、Compton散射光、等离子体的温度和密度作为调控光子禁带的新机制。研究结果表明,改变温度和等离子体密度分布可实现对等离子体光子晶体的光子禁带拓展,而Compton散射减小了这种拓展效应。Compton散射可使光子禁带向高频方向比散射前有较大的移动,能更好地实现等离子体光子晶体的高通滤波特性。

| Abstract: | Using multi-photon nonlinear Compton scattering model and finite-difference time-domain method,the influences of the density and temperature characteristics of band gap for un-magnetized plasma photonic crystals produced by multi-photon nonlinear Compton scattering are studied.A new mechanism of the modulation on the photonic band gap formed by incident light,Compton scattered light and plasma density and temperature is given.The results show that the photonic band gap of plasma photonic crystals can be dev... |
