Supertoroidal Electrodynamics [PDF]
2023 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2023 Toroidal electrodynamics is a recently established research area of electromagnetism that involves the study of doughnut-shaped excitations in matter and in free-space. Despite being first considered over 60 years ago, toroidal excitations have been often omitted from the description of matter as they were considered negligible, high order corrections.

We show that a not necessarily totally symmetric Bargman–Wigner second rank spinor field is able to accommodate a left–right symmetric U (1)L⊗ U (1)R Abelian gauge theory. We show that some features of the standard QED, such as vectorial gauge invariance, invariance under gauge transformation of the second kind, and the nonexistence of monopoles ...

The paper describes the physical phenomena involved in the conduction of electricity, with particular reference to living tissue. The conduction of electricity depends on the flow of charge carriers in the material, while the dielectric properties are due to the rotation of dipoles that can align along an applied electric field.

The electrodynamics of a substorm are analyzed using a crude one‐dimensional model. The discussion starts from the “standard interpretation“ scenario in which the plasma sheet collapses into a neutral sheet and magnetic merging occurs between the two tail lobes.

Gravitation and Electrodynamics
Physical Review, 1952In this paper Einstein's unified field theory is modified, and some of the physical implications of the new theory are examined. It entails: (1) a restriction of 4-current distribution, (2) an electromagnetic field consisting of short- and long-range parts, (3) a finite self-energy for the electron, (4) a classical description of pair production and ...

Electric charges interact via the electric and magnetic fields they produce. Electrodynamics is the study of the laws governing these interactions. The phenomena of electricity and of magnetism were once taken to constitute separate subjects. By the beginning of the nineteenth century they were recognized as closely related topics and by the end of ...

Development of quantum electrodynamics
Physics Today, 1966IN 1932, when I started my research career as an assistant to Nishina, Dirac published a paper in the Proceedings of the Royal Society, London. In this paper, he discussed the formulation of relativistic quantum mechanics, especially that of electrons interacting with the electromagnetic field.
