Abstract
Abstract A high power electromagnetic pulse driver for generating sub-microsecond rise time pulses having energy contents greater than 1 joule includes an electromagnetic pulse compressor and an electromagnetic shock line for compressing the leading edges of those pulses. The shock line may use non-linear materials whose permeability or permittivity vary greatly with varying field strength. One material whose permeability varies by a useful amount is metglass, an amorphous alloy of silicon and iron. The high power electromagnetic pulse driver may drive gas discharge lasers.
