Abstract: The finite temperature and density effect of vacuum polarization as well as the electromagnetic proptrty of thermal background medium are investigated. The vacuum polarization tensor the electrical permittivity and magnetic permeability are calculated strictly, and the strictly anlytical expression is presented which is applicable to all temperature and various density.
