In the electromagnetism [8], the set of Maxwell equations for vacuum gives relationships among the electric field E, magnetic field B, electric charge density [rho], and electric current density J as following:
In vacuum where electric charge density [rho] = 0 and electric current density J = 0, Eqs.
Four different sets of electric pulse parameters were employed by combining four different electric current densities based on the original cross-sectional area of the specimen (nominal electric current density [[rho].
14], the electroplastic behavior of metal under a pulsed electric current may be described using the applied electric energy per unit volume (electric energy density), which is a function of the electric current density and the pulse duration.
Equation (3) indicates that the scattering electric field is determined by the electric current density [?
J](p", p') denotes the ambiguity function (or point spread function) corresponding to the electric current density.
mu]] generated by the electric contour in the space to the infinity is possible to be calculated integrating only in the volume [upsilon] of the electric current density propagation
More adequate to physical ideas about law of distribution of the electric current density on the specimen surface should be considered the derivative, restored at the averaging interval, equal to double step [DELTA]l of measurement of the function [I.
Following the moment method procedure(4) and using point matching for the electric current density and global testing functions for the magnetic surface current densities, the three integral equations were transformed to a set of linear equations that were then solved to obtain the coefficients of the current density expansions.
Chapter 2 explains Maxwell's equations in the time and frequency domains, charge density distribution, electric current density distribution, Gauss's law for EM fields, EM boundary conditions and the plane wave solution.
