Even though one usually calculates capacitor losses with a complex Epsilon it still offends the principle of a constant speed of light. Maxwell's term c ² = 1/ε μ would even entail a physically unexplicable complex speed! By such an offence against basic principles every physicist is asked to search and to repair the mistake in the textbooks.
In the present treatise vortex losses get in the place of a postulated and fictive imaginary part of the material constant ε when the function of a microwave oven, welding of PVC foils or capacitor losses are to be explained. The responsible potential-vortices can be derived without postulate from approved physical laws and their existence can even be proved experimentally. Incidentally, they completely substitute for the vector potential A which has controlled electrodynamics as impurity ever since its introduction and blocked the look at a uniform theory of all interaction and physical phenomena. The new view alone justifies all efforts of rebuilding electrodynamics and removing the built-in contradictions.
