Smeared Field Description of Free Electromagnetic Field
نویسندگان
چکیده
Free electromagnetic fields, satisfying Maxwell's equations with no charges and electric currents, can be described by complex vector fields. In the standard formulation fields sharply dependent on position time, one obtains integrals that are mathematically ill-defined. This happens for massless Pauli--Jordan function, which is used to describe time evolution of appears in Poisson brackets classical difficulty solved introducing smeared as linear functionals test functions. this way, function becomes a~tempered distribution, allowing a rigorous analysis.

The wave-function description of the electromagnetic field
For an arbitrary electromagnetic field, we define a prepotential S, which is a complexvalued function of spacetime. The prepotential is a modification of the two scalar potential functions introduced by E. T. Whittaker. The prepotential is Lorentz covariant under a spin half representation. For a moving charge and any observer, we obtain a complex dimensionless scalar. The prepotential is a fun...
متن کاملKinetic theory of QED plasmas in a strong electromagnetic field II . The mean - field description
Starting from a general relativistic kinetic equation, a self-consistent mean-field equation for fermions is derived within a covariant density matrix approach of QED plasmas in strong external fields. A Schrödinger picture formulation on space-like hyperplanes is applied. The evolution of the distribution function is described by the one-particle gauge-invariant 4×4 Wigner matrix, which is dec...
متن کاملSeed Germination Enhancement of Zinnia (Zinnia elegans) Using Electromagnetic Field
The effect of electromagnetic field was examined on Zinnia (Zinnia elegans) seeds to enhance seed germination and early growth. The seeds were exposed to four magnetic strengths of 15, 100, 400 and 800 mT in four durations of 30, 60, 120 and 240 min. The experiments were carried out in two forms of laboratory germination and soil emergence. Results showed that magnetic field application enhance...
متن کاملQuantization of the Free Electromagnetic Field: Photons and Operators
Here electromagnetic fields are considered to be quantum objects. It’s an interesting subject, and the basis for consideration of interactions of particles with EM fields (light). Quantum theory for light is especially important at low light levels, where the number of light quanta (or photons) is small, and the fields cannot be considered to be continuous (opposite of the classical limit, of c...
متن کاملElement{Free Galerkin Method for Electromagnetic Field Computations
|Although numerically very e cient the nite element method exhibits di culties whenever the remeshing of the analysis domain must be performed. For such problems utilizing meshless computation methods is very promising. In this paper, a kind of meshless method called the element-free Galerkin method is introduced for electromagnetic eld computation. The mathematical background for the moving le...
