摘要
介电损耗是由于介质的绝缘不完善引起的,为了研究介电损耗所产生的影响,考虑带有漏电导的均匀有耗传输线。对BLT方程从频域到时域进行了推导,完善了时域上的BLT方程,目的是利用时域上的BLT方程对有瞬态信号源激励的传输线负载的响应电压进行计算,并通过这一计算结果来分析介电损耗所产生的影响。结果显示介电损耗的存在使终端负载的瞬态响应电压发生了衰减,并且这种影响是非线性的。
Dielectric loss is induced by imperfect dielectric insulation. In order to study the impact of the dielectric loss, and given the wide application of uniform loss transmission line with leak conductance, derivations to the BLT equation from the frequency domain to time domain is made in this paper. BLT equation in time domain is thus improved, with the purpose of making use of the equation to calculate load voltage of the transmission line with transient signal source, and analyze its impact on the dielectric loss. The results show that the attenuation of the terminal load transient response voltage occurs when the dielectric loss is present, and that this effect is nonlinear.
