The Concept of Reactive Power in Electrodynamics and Lagrange Structures of Wave Electromagnetic Fields

The representation of reactive power for nonharmonic electromagnetic fields and divergent equation of reactive energy conservation are obtained. It is proved that reactive power and reactive power density are the functional of action and negative Lagrange’s function density (Lagrangian) respectively. It is shown that this Lagrangian can be used for detection the same space structure of electromagnetic field as the structure of standing waves.
