Research on Millimeter Wave Microplasma Source Based on Two-dimensional Point-defect Reconfigurable Photonic Crystal

本文根据光子晶体缺陷理论,利用HFSS软件设计了一款基于二维可重构光子晶体阵列的毫米波微等离子体源,研究其谐振特性和电磁场分布等。仿真结果表明:晶格数目、介质柱半径和介质柱间距等参数对毫米波微等离子体源的S参数和电磁场分布等有较大影响;当谐振频率为76.02 GHz时,S_(11)为-25.11 dB,品质因数Q为400.11,最大电场强度可以达到2.3×10^(5)V/m。本文工作对基于二维可重构光子晶体的毫米波微等离子体源的进一步研究提供参考。

According to the theory of photonic crystal with vacancy,a millimeter wave microplasma source based on 2D point-defect reconfigurable photonic crystal array is designed by using HFSS software,and the resonant properties and electromagnetic field distribution of it are studied.The simulation results show that number and radius of dielectric column and lattice spacing have significant influences on S-parameters and electromagnetic field distribution of the millimeter wave microplasma source.When the resonant frequency is 76.02 GHz,the S11 value is-25.11 dB,the quality factor is 400.11,and the maximum electric field strength can reach 2.3×10^(5) V/m.The work provides a reference for research of millimeter wave microplasma source based on 2D point-defect reconfigurable photonic crystal array.
