Abstract

The time-domain step response of a transmission line (TL) with a dielectric insulator having a frequency-dependent conductance $G(\\omega )$ $\\propto \\omega ^{m} (m < 1)$ is analyzed. It is shown that for the case $m \\simeq 0.8$ , which describes many kinds of dielectric materials, the arctan-function represents an excellent approximation to the exact step-response function as given by Nahman [5] in the form of an integral. Based on the arctan approximation, a simple method for correlating the frequency-domain attenuation with the step-response rise time is presented. Experimental data on attenuation versus frequency and on corresponding step-response curves illustrate the application of the theoretical results.
