The scalar potential is a harmonic set of phase conjugate longitudinal EM waves. The dipole is a true negative resistor. The dipole's broken 3-symmetry initiates a spreading giant negentropic reordering of a fraction of the vacuum's energy.
Energy flow contours surrounding a transmission line.
Heaviside and Poynting energy flow components. The Heaviside component is often 10 trillion times the Poynting component, but is simply wasted in ordinary single-pass energy circuits. Negative resistance process v. positive resistance process. Lorentz's integration trick to discard the enormous Heaviside non-diverged energy flow component.
