A point charge is modeled as an electron in a spacetime governed by the Einstein–Maxwell equations, with electromagnetic self-energy that is ordinarily divergent. The relevant mech…

Let $(\rho,\overline{J})$ be a charge-current distribution. A source is called Poynting non-radiating or surface non-radiating according to the respective notions defined in the pa…

Let $d=4$ and consider the coupled electric, magnetic, and dielectric network obtained by joining oscillatory circuits on the edges of the grid, transformer cores along the $1$-dim…

Poynting-vector tilt conjecture. For any given carrier field, the corresponding effective light cones tilt into the direction of the Poynting vector of the field. Moreover, the hig…
