                         transmission lines with periodic LC and CL cells, taking into 
                         account ohmic losses in resistors connected in series to lumped 
                         capacitors and inductors. First order time differential equations 
                         are derived for current and charge, thus allowing analysis of 
                         transient regimes of the lines being excited by a pulse of 
                         arbitrary shape. In particular we examine the propagation 
                         characteristics of periodic lines in which identical unit cells 
                         are repeated periodically and also discuss the interpretation of 
                         positive and negative phase velocities associ-ated with the LC and 
                         CL topologies. Loss effects on the propagation bandwidths of both 
                         lines are also discussed, and it is shown that in the left-handed 
                         transmission line (CL configuration) the phase advance of the 
                         crest of the transmitted signal with respect to the source signal 
                         is due to the intrinsic dispersive nature of the CL line which, in 
                         contrast to the LC line, is highly dispersive at low propagation 
                         factors.",
