Abstract
A radio frequency (RF) wave generator includes a nonlinear transmission line and a pulse generator. The nonlinear transmission line has in order an input section, a magnetic section, and an output section. The magnetic section includes a nonlinear magnetic material. The pulse generator is configured to provide an input pulse to the input section which is converted to an RF wave by the nonlinear transmission line. A waveform of the input pulse is such that the generated RF wave is parametrically amplified.
