special relativity; geometric formulation of the relativistic electrodynamics

Sažetak
In the recently proposed invariant special relativity all physical quantities are defined without reference frames or, when some basis is introduced, every quantity is represented as a coordinate-based geometric 4D quantity comprising both components and a basis. The recent results of such geometric approach, that the standard transformations of the 3D E and B are not the Lorentz transformations and that Maxwell's equations with the 3D E and B are not Lorentz covariant equations, are discussed. Furthermore, we briefly review recently constructed geometric formulations of the relativistic electrodynamics that use the Faraday bivector field F, the 1-vectors E and B, the real multivector Psi =E-IcB and the complex 1-vector Psi =E-icB. All quantities in the geometric formulations are 4D quantities that are independent of the reference frame and of the chosen system of coordinates in it. Both the geometric approach and the usual approach with the 3D E and B are compared with the experiments. It is shown that this new geometric approach is in a complete agreement with the experiments, e.g., the Faraday disk, in all relatively moving inertial frames of reference, which is not the case with the usual approach with the 3D E and B.
