Study of electromagnetic radiation characteristic for non-magnetized plasma and magnetized plasma

Their electromagnetic instability dispersion function and electromagnetic radiation growth rate are studied in this paper for Maxwell distribution non-magnetized plasma and magnetized plasma. Theoretical research shows that non-magnetized plasma cannot emit electromagnetic wave while magnetized plasma can do. Also the variety of the growth rate with the radiation frequency, the plasma density and the plasma temperature is analyzed and discussed under different parameters for magnetized plasma. (authors)
