A constructal perception of the electromagnetic field

As a law of physics, the Constructal Law (CL) encompasses the electromagnetic field (EMF). Undoubtedly, CL manifests in the functioning principles or in improving the design of machines, engines, and systems where EMF is part of the energy - work - heat conversion chains. Moreover, the EMF constructal design empowers the designer with the freedom to develop more efficient engineered constructs through its actions, controllable by the project and energizing strategy, to adjust, adapt to, or alleviate constraints. In all these instances, EMF fluxes interact, merge, influence, and are influenced by other flows and fluxes. A vacuum system is hypothesized here as a state of extreme rarefaction of matter. EMF ' s constructal nature extends the CL construal from material and heat flows to fluxes that detach from their source and evolve in space and time (propagate) in ponderable or imponderable systems. Consistently to CL ' s perception scale (finite -size flow system, not infinitesimal, one particle, or sub -particle), the couplings and interactions between the electric and magnetic fields are assumed to be modeled by Maxwell-Hertz ' s laws. If ponderable matter occurs, it participates in this evolutionary process. It morphs and flows together with the fluxes. Constructal law may predict fluxes and flows, whether material or not.
