Correlation theory of stationary electromagnetic fields. Part IV — Second order conservation laws

  • P. Roman
Article

Summary

By imitating well-known techniques to obtain the energyequation in Maxwell’s theory, eight independent higher order conservation laws are found for the various second order correlation functions associated with stationary random electromagnetic fields. Two further conservation laws are deduced which involve the physically so significant energy coherence tensor and the flow coherence tensor.

Riassunto

Imitando le ben note tecniche per ottenere l’equazione energetica nella teoria di Maxwell, si trovano otto leggi di conservazione indipendenti di ordine superiore per le varie funzioni di correlazione di secondo ordine associate con campi magnetici stazionari casuali. Si deducono due ulteriori leggi di conservazione, che coinvolgono il tensore di coerenza dell’energia, cosi significativo dal punto di vista fisico, ed il tensore di coerenza del flusso.
