Abstract

In this paper, a novel closed form expression is derived to find the Green' s function of a horizontal electric current in a parallel-plate waveguide. It is achieved by expanding the Green' s function into a series of Gaussian functions. This new method is called the Gaussian Green' s function (GGF) method. The main advantage of the GGF method lies in its precision as well as rapid convergence. Numerical results confirm that the closed form expression yields less than 0.2% error compared to the numerical integration of the spectral integral. Furthermore, it is verified that this method can be in excellent agreement with the complex images (CI) method.

平行板波导中电流格林函数的高斯展开

本文推导了平行板波导中水平电流的格林函数的一种新颖的封闭表达式。它是通过将格林函数展开成一系列高斯函数来实现的。这种新方法称为高斯格林函数(GGF)方法。GGF方法的主要优点是精度高，收敛速度快。数值结果证实，与谱积分的数值积分相比，封闭形式表达式的误差小于0.2%。实验结果表明，该方法与复合图像(CI)方法具有较好的一致性。
