Abstract

The paper is dedicated to the numerical study of the dependence of plasma antenna resonance wavelengths on pressure. The study was carried out by simulating a RF capacitively coupled plasma with the Comsol Multiphysics software in one- dimensional formulation. Based on the calculated electric current in the plasma, the directional pattern and axial distribution of the electromagnetic field were found by solving Maxwell’s equations in a 2D formulation. The results showed that one of the advantages of plasma antennas is the transmission of waves at significantly longer wavelengths compared to metal antennas of similar geometry.

压力对等离子体天线共振波长的影响

摘要本文致力于对等离子体天线谐振波长与压力的关系进行数值研究。研究采用 Comsol Multiphysics 软件对射频电容耦合等离子体进行一维模拟。根据计算出的等离子体中的电流，通过求解二维形式的麦克斯韦方程，找到了电磁场的方向模式和轴向分布。结果表明，与类似几何形状的金属天线相比，等离子体天线的优势之一是可以传输波长更长的电波。
