I strongly suggest you check the library for the three volumes of Modern Nonlinear Optics, 2nd edition, Edited by Myron W. Evans, Wiley, 2001 and study the article we referenced (there are also many other interesting articles). Or you can look for additional material on website www.aias.us.
Standard Maxwell-Heaviside electrodynamics has a great many shortcomings! E.g., it assumes that every charge freely creates --- from nothing at all --- all the energy it continuously pours out to form its associated EM fields and potentials and their energy, expanding radially outward at light speed from the moment the charge is created. In short, Maxwell-Heaviside classical electrodynamics assumes that every joule of EM field energy and EM potential energy in the universe is made by a forbidden perpetual motion machine called a "source charge". Few texts even mention this problem anymore, since they never solved the problem. It has been solved since 1957 in particle physics, if one models the active vacuum exchange with the charge and also includes the known polarization of the vacuum (the clustering of virtual charge of opposite sign around any "isolated" observable charge). With the included QFT virtual clustering, one is dealing with a dipolarity and therefore with the broken symmetry of opposite charges. That means that the "isolated charge" continuously absorbs EM energy from the seething vacuum, converts it (coherently integrates it) into observable photons, and re-emits the energy as observable photons emitted in all directions, thereby establishing the associated EM fields and potentials.
Simply try finding anything in any conventional classical EM textbook on the exact mechanism by which the charge creates its fields and potentials and their energy, and from where it receives the input energy. Either the charge totally falsifies the entire conservation of energy law, or else the classical EM model is in serious need of revision and extension to include the active vacuum and broken symmetry.
There are dozens of other shortcomings and failures of the Maxwell-Heaviside model. Hence for finer work, one really does need a higher group symmetry EM model, such as O(3) or SU2XSU2, etc. Higher symmetry EM models have been developed for particle physics, because the classical theory simply fails to describe a great deal of the physical phenomena encountered. There is an increasing number of electrodynamicists that are beginning to work in such higher symmetry EM models, with the result that electrodynamics is still a vitally developing field.
