US12429312 - Frequency and waveform agile microwave devices

Implementations of disclosed systems and methods are capable of changing the frequency or other waveform characteristics dynamically based on receiving feedback about the effect of an electromagnetic pulse radiation on a target electronic device. Various implementations can be configured to emit electromagnetic pulses at a single radio frequency or a plurality of radio frequencies. For example, the frequency of the carrier electromagnetic radiation in a single pulse can change during the pulse interval. As another example, a single electromagnetic pulse can comprise a frequency comb with two or more frequencies.

The patent describes a system designed to emit electromagnetic radiation that can dynamically adjust its frequency based on feedback from its interaction with a target electronic device. This system includes components such as a programmable RF generator, amplifiers, and an antenna, all configured to disrupt the target device by emitting pulses at varying frequencies within a specified range.
