On the Solution of Maxwell's First Order Equations
Wolfgang Engelhardt
In an attempt to solve Maxwell's first order system of equations, starting from a given initial state, it is found that a consistent solution depending on the temporal evolution of…

Gauge Invariance in Classical Electrodynamics
Wolfgang Engelhardt
The concept of gauge invariance in classical electrodynamics assumes tacitly that Maxwell's equations have unique solutions. By calculating the electromagnetic field of a moving pa…
