Analyse temporelle des lignes de transmission non uniformes avec effet de peau

This paper deals with a computational approach, based upon centered points finite-difference time-domain technique, for evaluating voltages and currents along nonuniform planar transmission lines terminated with arbitrary loads. To improve the accuracy of the method, the skin effect has been included into the algorithm by means of the approximation of the conductor internal impedance. Some configurations of nonuniform planar lines have been analyzed in order to show different aspects of the efficiency of this computational procedure.
