A spherical plasmoid with a diffuse boundary in a linearly polarized quasistatic electromagnetic field

The problem of a spherically symmetric plasmoid placed in a linearly polari zed uniform quasistatic electromagnetic field is considered. The electric f ield in the vicinity of a plasmoid with a Gaussian electron density distrib ution is calculated. The results of calculations are compared with the know n solution for a spherical plasmoid with a uniform density. The possibility of the transformation of an initial plasmoid that arises in an electrodele ss microwave gas discharge into a microwave streamer is discussed. (C) 2001 MAIK "Nauka/Interperiodica".
