“…The role of field-dependent permittivity is also evident. With increasing voltage for any sample, the higher electric field lowers the permittivity [as per (6)] and hence works to lower the overall capacitance per unit length. The capacitance will be lowest for the largest applied-voltage amplitudes.…”

“…However, high-voltage solid-state switches suffer from several problems such as "lock-on," filamentation, and device degradation [5]. Moreover, the lifetime of these devices is relatively short, and their high-voltage capability is limited [6]. High-pressure hydrogen-filled [7] or oil-filled [8] spark gaps are capable of switching very high voltages in less than 200 ps but are limited in their pulse repetition rate.…”

“…In the past, transmission lines containing ferrites with nonlinear magnetic materials have received some attention [15], [16]. Although it has long been recognized that transmission lines 0093-3813/$25.00 © 2008 IEEE containing nonlinear ferroelectric dielectrics could also be used as nonlinear components in high-voltage systems [6], a few experimental works or theoretical analyses appear to have been published.…”

The generation of high-voltage electrical pulses with very fast rise times is important for several pulsed-power applications. Although several techniques and devices have been used to generate ultrashort rise-time pulses, most suffer from problems relating to reliability, lifetime, and power-handling capacity. Here, the concept of using nonlinear transmission lines is used for attaining ultrashort rise times and pulse sharpening. Numerical simulations are carried out using barium strontium titanate as the dielectric system. The concept is based on using the nonlinear voltage-dependent capacitance of the granular material. The presence of internal grains increases the breakdown strength and also provides for a nonlinear voltage-dependent capacitance that depends on the internal grain size. The output characteristics of transmission lines based on such nonlinear material are simulated. Our results clearly demonstrated rise-time shortening. The results were in agreement with some published experimental data.Index Terms-Barium strontium titanate (BST), highvoltage pulsing, nonlinear transmission lines, rise-time sharpening, Voronoi network model analysis.

“…The high fields can be intentionally applied such as for photoconductive switches, [3][4][5][6] or due to unwanted transient fields such as during electrostatic discharge ͑ESD͒. 7 Much work has been reported by several groups trying to increase the hold off voltage of silicon.…”

“…Lastly, we analyze previously reported experimental results in light of the theory and show how the risetime of the UWB pulse and the parameter a compare. 2 Performance Parameter As we described above, the most universal configuration is that of a switch bridging 2 identical TL's with the switch and the TL's all having the same width w, (see Figure 1). Wrapping w around a cylinder corresponds to a coaxial geometry.…”

We present a theoretical discussion of the performance of photoconductive switches mounted in a matched transmission line structure, which addresses issues of risetime and power density. In the analysis we define a switch performance parameter, a , which results in a recipe for optimizing the performance of photoconductive switches. We also discuss the limits on a due to materials' properties and conclude with a discussion of experimental life-testing and a comparison between the theory and experimental results.
