Originální abstrakt

Power-cable fault localization using time-domain reflectometry requires an efficient computational technique for the evaluation of pulsed electromagnetic fields in cylindrically layered structures. A robust way to handle the problem is to perform a contour complex integration at a number of frequency points and carry out an inverse fast Fourier transformation with respect to time. Alternatively, one may employ a slowness representation along the cable axial direction in combination with a one-sided Laplace time transformation and obtain time-domain results more or less directly. This is exactly the main subject of the present contribution in which it is shown that the pulsed electromagnetic response of a cylindrically layered cable can be constructed with the aid of Cagniard-DeHoop (CdH) technique and a numerical Laplace-transform inversion method in the intermediate step.
