1. A high-power pulsed electromagnetic field (PEMF) applicator system, the system comprising:
a base housing comprising a controller configured to generate and multiplex a high-power PEMF signal, the base housing comprising a tuned switching power amplifier configured to generate a pulsed drive signal, and a plurality of radio-frequency (RF) amplification stages; and
two or more applicators coupled to the plurality of RF amplification stages in the base housing, wherein each applicator comprises:
a coil circuit configured to emit the high-power PEMF signal; and
a feedback sensor configured to directly measure a field strength from the coil circuit and transmit a feedback signal based on the field strength to the RF amplification stage connected to the applicator, wherein the feedback signal modifies an operation of the RF amplification stage to increase or decrease an intensity of the emitted high-power PEMF signal,
wherein the two or more applicators are configured to emit non-overlapping high-power PEMF signals based on the multiplexed high-power PEMF signal.
