Abstract : Computer simulations of microwave coupling to a nitrogen breakdown plasma have been performed at 25 Torr. Non-hydrodynamic ionization fronts are observed to propagate toward the radiation source under a variety of circumstances. Free nitrogen breakdown simulations in a spherical system show the propagation velocity of the breakdown wave can be as high as 5 x 10 to the 6th power cm/sec. An elementary theory is used for estimating the speed of the breakdown wave in one dimension. The results are in resonable agreement with breakdown experiments. (Author)
