OSTI ID:7192074
We used numerical calculations to determine the effects of air breakdown on the coupling of intense microwave pulses passing through apertures. Our calculations are based on a set of Maxwell equations and electron-fluid equations. Results show that the air-breakdown threshold energies in apertures have a functional dependency on pressures similar to that of air-breakdown threshold energies in the atmosphere. We present variations of the transmitted energies of intense microwave pulses passing through apertures as a function of incident-field intensity and aperture size. The effects of secondary emission on the air-breakdown threshold energies around apertures are also discussed.
