Abstract

This paper presents a new method of frequency-domain sensitivity analysis for parabolic lossless nonuniform transmission line. The frequency-domain sensitivity formulas are expressed by the line port voltages and currents. Therefore this method can avoid the possible numerical instability caused by negative capacitance in Kuroda´s identity in Liang Guishu et al. (2004). Examples and comparisons with sensitivity determined by perturbation are presented
