真空中螺旋天线的矢势分析

Vector potential analysis of the helicon antenna in vacuum

Robert W. Johnson

摘要:

螺旋天线是电力推进领域中的公知装置。在这里,我们研究了在真空中产生的矢量势这样的天线具有典型的尺寸参数。进行了静态和动态分析。在通常的工作频率和稍高的工作频率下进行动态计算。在较高的频率下,发现电磁能脉冲沿着圆柱轴在任一方向上传播。讨论了螺旋天线作为燃烧等离子体的射频注入装置的可能适应性。

英文摘要:

The helicon antenna is a well-known device in the field of electric propulsion. Here we investigate the vector potential produced in vacuum by such an antenna with typical size parameters. Both a static and a dynamic analysis are performed. The dynamic calculation is evaluated at both the usual operating frequency and one which is slightly greater. At the higher frequency, a pulse of electromagnetic energy is found to propagate along the cylindrical axis in either direction. The possible adaptation of the helicon antenna as a RF injection device for burning plasma is discussed.
