Calculation of three-dimensional electromagnetic fields involving laminar eddy currents

The formulation of a method to solve steady-state electromagnetic field problems involving laminar eddy currents is described. Iron nonlinearity is included. The formulation is implemented using finite elements and the problems associated with the solution of the resulting nonlinear equations discussed. Experiments with a Newton-Raphson iteration and modifications to it are described and a best...

Three - Dimensional Electromagnetic Inverse Scattering

A numerical algorithm for the reconstruction of the permittivity of a three-dimensional penetrable object from scattering data is presented. The reconstruction algorithm is based on the local shape function method (LSF) combined with the conjugate gradient method with FFT (CGFFT). The nonlinearity due to the multiple scattering is accounted for in an iterative minimization scheme. Numerical exa...

Three-dimensional accelerating electromagnetic waves.

We present a general theory of three-dimensional non-paraxial spatially-accelerating waves of the Maxwell equations. These waves constitute a two-dimensional structure exhibiting shape-invariant propagation along semicircular trajectories. We provide classification and characterization of possible shapes of such beams, expressed through the angular spectra of parabolic, oblate and prolate spher...

Neutrino spin-flavor oscillations in electromagnetic fields of various configurations

We study spin-flavor oscillations of Dirac neutrinos with mixing and having non-zero matrix of magnetic moments in magnetic fields of various configurations. We discuss constant transversal and twisting magnetic fields. To describe the dynamics of Dirac neutrinos we use relativistic quantum mechanics approach based on the exact solutions to the Dirac-Pauli equation in an external electromagneti...
