             abstract = "A nonlinear lumped element transmission line (NLETL) that consists 
                         of a nonlinear LC ladder network whose capacitors are nonlinear 
                         and inductors are linear can be used to produce oscillating 
                         pulses. This article describes the implementation of an 
                         oscillating pulse generator based on such high voltage nonlinear 
                         capacitive lines (NLCL) using commercial-off-the-shelf (COTS) 
                         components. Instead of using complex pulse forming networks or 
                         pulse forming lines, a storage capacitor and a fast semiconductor 
                         switch are used to provide an input pulse onto the cascading 
                         LC-elements of the NLCL with good approximation of a rectangular 
                         pulse-shape. The design of the NLCL is based on the NLETL circuit 
                         model that was developed earlier in-house. Experimental results 
                         are compared with simulations predicted by this NLETL model. The 
                         voltage modulation and the frequency content of the output pulses 
                         are analyzed. The conventional single NLCL produces a signal with 
                         a DC offset and a decoupling capacitor is needed at the end of the 
                         line to extract the AC component before injecting onto a load such 
                         as an antenna. A novel method of directly extracting the AC 
                         component without the use of a decoupling capacitor is proposed 
                         and investigated. Results of this direct AC extraction, which show 
                         the possibility of better performance, are discussed. The 
                         frequency tunability of this nonlinear line was also 
                         demonstrated.",
