Abstract:

The breakdown plasma was observed to travel towards the source with a velocity of 4.6 x 10 to the sixth power cms. This was a result of the formation of a sufficiently dense plasma to reflect the incident microwaves. This decoupling mechanism makes localized heating of air by microwaves extremely difficult, if not impossible. Rapid heating of the air is further minimized by the large amount of energy trapped by nitrogen vibrational states. These states lock-up energy for long periods of time, preventing its transfer to kinetic energy. Observation of the electron temperature Te - 3.8 eV confirmed this. These two factors prevent the formation of large shock waves due to rapid heating of the air. Author
