摘要
基于Beam Liu Tesche方程(以下简称BLT方程),采用离散化方法来求解双导传输线的频域和时域终端响应。对于离散化的双导线模型,应用Agrawal模型分布源,首先获得了BLT方程在频域上的离散化计算公式。接着采用Fourier逆变换,获得BLT方程在时域上的离散化计算公式。采用这两个离散化计算公式,当知道在导线上的激励源分布的离散数据时,就可以计算线路终端频域或者时域的感应电压和电流。最后针对平面波激励源进行数值仿真试验。
The terminal response of two-wire transmission line in frequency domain and time domain are calculated by the discretization method based on the BLT equation. For the discretization model of twowire transmission line,the discrete formula of the BLT equation in the frequency domain is obtained under the distribution source of the Agrawal model. Then the discrete formulation of the BLT equation in the time domain is obtained by the inverse Fourier transformation. With these two discrete calculation formulas,the terminal response of voltage and current in frequency domain or time domain can be calculated when the discrete data of excitation source distributed on the line is known. Finally,numerical examples are presented for the plane wave illumination.
