填充等离子体波纹波导色散曲线计算软件的设计

The Design for a Software Calculating the Dispersion Curves of a Plasma Loaded Corrugation Wave-Guide

从一种正弦波纹波导慢波结构的色散方程理论推导出发,设计了在不同结构参数、有无电子注以及填充不同等离子体浓度的情况下,计算其色散曲线的专用软件。该软件除了具有传统的数值计算功能外,提供了一个较为友好的图形用户界面。该界面直接显示该波纹波导的结构图,同时用户可以通过该界面很方便地修改各主要参数,比较不同情况下得到的色散曲线,以获得优化的参数选择。

A software calculating the dispersion curves for a special kind of slow-wave structure(SWS)——sine shape corrugation wave-guide was designed in this paper. Before that, the deducing of the dispersion equation was introduced. The software offered a friendly graphical user interface(GUI) as well as the numerical calculating kernel. Through the GUI, the user can view the SWS' structure, edit the prime parameters such as structure parameters, plasma densities, choose whether driven by electron beam or not directly. In the GUI, user also can observe the comparison between the curves calculated under the different situations and choose the optimum parameters finally.
