High power radio frequency field generation with nonlinear transmission lines

This paper analyzes the mechanism of radio frequency(RF) field generation using nonlinear transmission lines. According to soliton theory, relevant parameters affecting the field generation are investigated systematically using circuit simulation method. It is found that an increase in the input voltage, and a decrease in the inductance and nominal capacitance of the nonlinear transmission line can increase the frequency of the generated RF field, and an increase in the nonlinear rate of the capacitance can increase the peak voltage and higher frequency components. A nonlinear transmission line, which can generate an RF field with 0.8 GW power and 19.42 MHz frequency, is then designed.
