在本文中，我们首先表明，注入到相互作用区域的等离子体形成的等离子体密度的周期性分布，被称为自感密度光栅，并施加在两个强大的反向传播波调制的介电常数的周期性扰动。接着，我们证明了由自感生分布反馈形成的准周期等离子体密度光栅具有等离子体光子晶体（PPC）的特性。因此，利用自感准周期等离子体密度光栅形成PPC是一种可行的制作方案。基于等离子体密度光栅的等效模型，导出了等离子体密度光栅的色散关系，并对一种简单情况进行了计算和讨论。
In the present paper, we first show that the plasma injected into the interaction region forms a periodical distribution of the plasma density that is called self-induced density grating and exerts a periodic perturbation on the dielectric constant under two strong counterpropagating waves modulation. In succession, we demonstrate that the self-induced quasi periodic plasma density grating formed by the self-induced distributed feedback possesses the properties of plasma photonic crystal (PPC). Therefore, the formation of PPC by the self-induced quasi periodic plasma density grating is a feasible fabrication scenario for PPC. Based on an equivalent model of the plasma density grating, a dispersion relation is derived, and a simple case is calculated and discussed.
