Ferrimagnetic Shocklines for a Solid-State High-Power Microwave System
The DoD currently has a need for SWaP-favorable solutions for pulse sharpening of high-voltage impulses. Current methods of high-voltage pulse sharpening from solid-state pulse generators rely on commercial off the shelf (COTS) devices. However, these devices are limited in the amplitude of the impulses they can sharpen and have limited operational lifetimes. The DoD has a need for a robust pulse sharpening solution which may be optimized for specific high-voltage impulses and can scale to sharpen impulse amplitudes greater than 100 kVs. Ferrimagnetic shocklines offer the potential to meet this requirement and deliver a capability which may be optimized and can scale to the required high-voltage amplitudes as well as handling pulse repetition rates on the order of 10s of kHz. Proposed pulse sharpening solutions should offer the capability to sharpen nanosecond pulse width high-voltage impulses to generate outputs with 10%-90% rise time pulses on the order of 150 picoseconds and full width half maximums of 500 picoseconds.
