Claim 0:
1. A signal generator comprising:
a plurality of voltage sources for generating a plurality of source signals;
a plurality of switch groups for converting the plurality of source signals into a plurality of modulated signals by actuating one or more switches of the plurality of switch groups, the plurality of modulated signals being capable of providing a desired power spectral density;
at least one switch network driver for providing a plurality of modulation signals to the plurality of switch groups, the one or more switches of the switch groups being actuated by the plurality of modulation signals;
a signal combining unit comprising at least one transformer, the signal combining unit for combining one or more of the plurality of modulated signals into a combined signal and transforming the combined signal to have the desired power spectral density, thereby providing at least one output signal; and
a processor configured to:
determine a desired output signal of the at least one output signal having the desired power spectral density; and
control the plurality of voltage sources, the at least one switch network driver, and the signal combining unit based on the desired output signal;

wherein when the at least one output signal is applied to a load having a frequency-dependent impedance, at least one standing electromagnetic wave is produced along a length of the load, the at least one standing electromagnetic wave comprises at least a partial standing electromagnetic wave.
