        Frank, 
        
          
        
        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.  
        
          Best wishes,
