Abstract

The finite difference time domain (FDTD) technique is used to analyze the transmission characteristic in GTEM cells in a polar coordinate system. To simulate the propagation of the wave at the terminal section a first order absorption boundary condition was implemented. The scattering coefficient and characteristic impedance are calculated. The analysis has been carried out in the frequency domain response with pulse source by means of a discrete Fourier transform.

GTEM细胞传输特性的时域有限差分评价
利用时域有限差分(FDTD)技术分析了极坐标系下瞬变电磁体的传输特性。为了模拟波在终端段的传播,采用了一阶吸收边界条件。计算了散射系数和特性阻抗。利用离散傅里叶变换对脉冲源的频域响应进行了分析。
