1 ECE Engineering Model The Basis for Electromagnetic and Mechanical Applications Horst Eckardt, AIAS Version 4.1,

2 ECE Field Equations Field equations in tensor form With –F: electromagnetic field tensor, its Hodge dual, see later –J: charge current density –j: „homogeneous current density“, „magnetic current“ –a: polarization index –μ,ν: indexes of spacetime (t,x,y,z)

3 Properties of Field Equations J is not necessarily external current, is defined by spacetime properties completely j only occurs if electromagnetism is influenced by gravitation, or magnetic monopoles exist, otherwise =0 Polarization index „a“ can be omitted if tangent space is defined equal to space of base manifold (assumed from now on)

4 Electromagnetic Field Tensor F and are antisymmetric tensors, related to vector components of electromagnetic fields (polarization index omitted) Cartesian components are E x =E 1 etc.

25 Properties of ECE Equations The ECE equations in potential representation define a well-defined equation system (8 equations with 8 unknows), can be reduced by antisymmetry conditions and additional constraints There is much more structure in ECE than in standard theory (Maxwell-Heaviside) There is no gauge freedom in ECE theory In potential representation, the Gauss and Faraday law do not make sense in standard theory (see red fields) Resonance structures (self-enforcing oscillations) are possible in Coulomb and Ampère-Maxwell law
