摘 要: 探讨电磁波时域积分方程(time domain integration equation,TDIE)算法在等离子体中的应用,简单介绍边界元法(boundary element method,BEM)、TDIE算法的基本原理,推导在等离子体介质中的场域积分方程,并且讨论求解方程的时间步进(marching�on�in�time,MOT)法及其加速算法时域平面波(plane wave time domain,PWTD)法。相比频域算法,时域算法具有下列优点:更为适合宽带信号的研究;更为适合大规模并行计算;可以更为直观地理解场的相互作用;可以方便、直接地处理非线性媒质和时变媒质的散射问题和辐射问题。
关 键 词: 电机及控制工程;等离子体;时间步进法;时域积分方程法;时域平面波法

Abstract: This paper discusses the application of electromagnetic wave propagation in the plasma media using algorithm of time domain integration equation (TDIE). The keystones of boundary element method (BEM) and TDIE are briefly presented. The integration equation of field domain in plasma media is deduced. The marching�on�in�time (MOT) and plane wave time domain (PWTD) when solving the equation are also discussed. Compared to frequency�domain algorithms, time�domain algorithm has the following advantages: more suitable for broadband signals; more suitable for large�scale parallel computing; can be more intuitive in understanding of market interactions; and can easily and directly deal with non�linear medium and the scattering of time�varying media and radiation.
Key words: electrical dnd fontrol engineering; plasma; marching�on�in�time method; time domain integration equation method; plane wave time domain method
