             abstract = "Dielectric nonlinear transmission lines (NLTLs) have demonstrated 
                         great potential in RF generation. Their main characteristic is 
                         that they do not require an electron beam to operate. However, 
                         there are some key points in their operation not clarified yet. 
                         For instance, they generate output oscillations with frequency at 
                         half the line Bragg frequency for a high number of sections 
                         (n>30); however, for smaller n (=10) this frequency appears to be 
                         near the Bragg frequency1. In this work, it will be demonstrated 
                         that this effect has to do with the spreading of train of solitons 
                         travelling through a long line (i.e. with a high number of 
                         sections). In addition, it will be shown that for a line with 
                         higher n, the nonlinearity factor k of the dielectric can be very 
                         close to unity, which means that capacitors with more stable 
                         capacitance can be used. This effect has been observed in 
                         practice, as it is easy to produce a train of solitons with higher 
                         amplitudes for a line built with a large number of sections2. 
                         Finally, the points discussed above will be checked experimentally 
                         by measuring the standard FFT of the signal along a varactor diode 
                         NLTL made with 30 sections, operating at the output frequency 
                         around 50 MHz.",
