有耗介质半空间上线天线的输入阻抗

The Input Impedance of Thin-Wire Antennas above Lossy Media

运用近年来发展起来的矩阵束法得到空间域格林函数的近似解，并结合感应电动势法，给出了有耗介质半空间上垂直放置的线天线输入阻抗的闭合表达式。数值结果表明本文运用的方法对分析垂直于地面以及有耗或无耗介质半空间上的线天线是有效的。

The Matrix Pencil Method is used to get the polynomial approximations of the spatial Green's function, and the close form solution for the input impedance of thin-wire antennas above lossy media is derived through the induced EMF method. Numerical results show that the method proposed in this paper is accurate and effective for the vertical thin-wire antennas above lossy or lossless dielectric half space.
