De Broglie’s Double-Particle Photon

Establishment of an LC equation and of a local fields equation describing per­manently localized photons from the analysis of kinetic energy circulation within the en­ergy structure of the double-particle photon that Louis de Broglie hypothesized in the early 1930's. Among other interesting features, these equations provide a mechanical explanation to the localized photon properties of self-propelling at the speed of light and of self-guiding in straight line when no external interaction tends to deflect its trajectory. This paper summarizes the seminal considerations that led to the establishment of the mechanical conversion processes involving electromagnetic energy and mass from electromagnetic photon emission to nucleon construction from the trispatial geometry perspective.
