The concept of active and reactive energy of electromagnetic waves are introduced to the scientific circulation and complete the formation of concepts of the wave theory as a section of electrodynamics. Algorithm for separation of active and reactive energy of electromagnetic waves is mathematically and physically justified. Importance of such separation of active and reactive energy of electromagnetic waves is shown on the example of the propagation velocity of wave energy in a lossy medium. Results can be also applied to analysis of wave propagation processes in the intermediate zone of Hertzian dipole and adjacent reagions.References
