Subnanosecond pulse propagation in a Goubau line immersed in a lossy dielectric medium

The distortion and attenuation of a subnanosecond pulse propagating along a Goubau line immersed in a lossy dielectric medium is considered in the letter. The pulse response characteristics of this line have been analysed by using a fast Fourier transform algorithm. The results of this investigation have important implications in the design of high-resolution guided-wave radar systems.
