The simulation and probing technique of large-scale plasma in atmosphere

Large-scale plasma in the atmosphere is thermodynamic system which is made up of ions, atoms, molecules and particulate matter. The plasma which has the characteristics of thermal movement and electromagnetic interaction can be used to signal interference, invisibility and wireless communication. First, the report provides that the generation of plasma by ionizing of easily ionized metals under high temperature and high pressure, the diffusion of plasma under shock wave and the temporal and spatial distribution of plasma parameters, such as density, temperature and collision frequency. Second, the advanced composite gunpowder forms large-scale aerosol plasma by the method of continuous generating plasma, particles and gases. And the atmospheric Langmuir double probe is used to detect physical parameters of aerosol plasma, such as the density distribution of ion and electron, the temperature distribution of ion and electron. Tests showed that gunpowder of 10g is able to form the aerosol plasma with radius > 50cm and the density of ion > 10(13)/cm(3).y
