The Effect of Electronic Halos on the Scattering Properties of Solid Particles in the Microwave Range

Physical processes occurring in air disperse media with solid particles in a laser channel during thermal emission of electrons from the particle surface and primary optical breakdown are considered. Changes in the refractive index during the formation of plasma halos around radiation-heated microparticles are estimated. A possibility of weak ionization of an air medium at a distance of several centimeters from the breakdown area due to the ionization of NO molecules and thermochemical reactions is shown.
