... by introducing the magnetic vector potential A , with the Coulomb gauge, and the electric scalar potential φ, so that the electric field E can be expressed as: Equation 1 where the magnetic vector potential A is given by the superposition integral Equation 2 In these expressions, J...

... and diffusion coefficients as functions of the electric field. The integral‐differential equations derived by means of the above mentioned method are numerically solved using a combination of spherical harmonics functions and finite‐difference operators. The Kane model for the electron band structure is assumed...

... zero at lower deposition due to decreasing of electric field in the electron‐emitting zone. As an example we have analyzed a 110kV GIS barrier. Figure 1 shows a computer‐generated image of a typical three‐phase barrier between two GIS compartments for different pressures (with sealed supporting...

...Jarmila Dedkova; Libor Dedek; Juraj Valsa A new finite element method (FEM) approach is used to evaluate transient electric field based on a surge wave in a dissipative open region. Instead of the solution of the basic equations in the time domain, the Laplace transform inversion is used to model...
