| 摘 要： | 根据激光等离子体天线工作原理给出了电磁分析模型,以电场作为未知函数建立了频域体积分-微分方程,用脉冲基函数和点匹配函数的矩量法（MOM）将之转为线性代数方程组。求解中应用快速傅里叶变换（FFT）和共轭梯度法（CGM）,以降低所需计算机内存和减少CPU计算时间。算例表明：该法计算的结果与Mie级数解析解和其他文献结果吻合较好。

| Abstract: | The near electromagnetic model of laser plasma antenna was put forward based on the operating principle of the antenna in this paper.A general volume integro-differential formulation of electric field for the scattering problem was deduced.The system of linear algebraic equations was achieved by using the numerical method of moment(MOM) with pulse basis functions and a Dirac testing function.To reduce storage and CPU time,the conjugate gradient method(CGM) and fast Fourier transform(FFT) technique were used... |
