Nonlinear transmission line-driven apparatus for short-pulse microwave exposure of aerosolized pathogens

Nonlinear transmission line-driven apparatus for short-pulse microwave exposure of aerosolized pathogens

A system capable of exposing a flowing aerosol stream to short duration (2–4 ns), high-power RF waveforms is described. The system utilizes a C-band gyromagnetic nonlinear transmission line source having peak power outputs ranging as high as 80 kW at a center frequency of 4.2 GHz. RF electric field...

Zusammenfassung:A system capable of exposing a flowing aerosol stream to short duration (2–4 ns), high-power RF waveforms is described. The system utilizes a C-band gyromagnetic nonlinear transmission line source having peak power outputs ranging as high as 80 kW at a center frequency of 4.2 GHz. RF electric field magnitudes of up to 280 kV/m ± 17% are achieved within the aerosol flow region of the RF exposure apparatus.
