Abstract :
The simplest dispersion laws for dissipative media, density of electromagnetic energy, phase and group velocities been considered. It has been shown that group velocity may exceed the velocity of light. Also it has been shown that for polar dielectrics with abnormal positive dispersion described by Deby´s formula the velocity of energy coincides with phase velocity
