Plasma photonic crystals (PPCs) have been a hot research topic in the band gap (BG) material field in recent years due to their unique advantages, such as the feasibility of changing the parameters and hence the properties of the materials with respect to traditional photonic crystals (PCs). In this paper, we focus mainly on the effects of some types of defects introduced in PPCs on the changes in BG characteristics of microwave (MW) transmittance. The research is carried out using numerical simulation with a one-dimensional finite-difference time-domain (FDTD) method, and six types of defects, including a lattice-constant defect, radii-ratio defect, additional-column defect, column-width defect, plasma-frequency defect, and electron-collision-frequency defect, are concerned. It transpires that introducing a defect in a PPC in different manners may realize the symmetric change, alternative change, shifting, generating, transforming, disappearing, and attenuating of BGs in transm...

等离子体光子晶体中的缺陷对微波透射特性的影响

等离子体光子晶体（PPC）近年来因其独特的优势而成为带隙（BG）材料领域的热门研究课题，例如相对于传统光子，可以更改参数并因此改变材料的性能。晶体（PC）。在本文中，我们主要关注于PPC中引入的某些类型的缺陷对微波（MW）透射率BG特性变化的影响。该研究使用一维有限差分时域（FDTD）方法进行的数值模拟以及六种类型的缺陷进行，包括晶格常数缺陷，辐射比缺陷，附加列缺陷，列宽缺陷，等离子频率缺陷和电子碰撞频率缺陷。
