A Quaternary Wave Theory of Electromagnetic Fields: A Theory on Propagation of Electromagnetic Fields in Vacuum

Dağ B.

There are still some unclarified points in physics such as propagation of electromagnetic waves in free medium (vacuum), negative energy states emerging from Dirac’s relativistic solution of particle position and initial formation of universe, which was hypothesized by Hawking as formation from zero (nothing) as absolutely equal positive and negative energy mediums. In this paper, by using Poynting theorem and a new vector calculus conditional identity, energy flow in a simple electromagnetic energy conversion system will be defined in an alternative equal form, where, in this alternative form two new fields can possibly be defined. Later, new fields will be described in the form of modified Maxwell’s equations and it will be shown that in this modified form of electromagnetic theory, the wave behaviour of electromagnetic fields become consistent with the fundamental mechanical wave concept of simple harmonic motion such that in this case the electromagnetic energy oscillates between positive and negative energy during propagation in vacuum. The concept of negative energy, emerging in the electromagnetic waves, is evaluated finally. Versiyon : 1
