Electromagnetic scattering from anisotropic materials, part I: General theory

IEEE Transactions on Antennas and Propagation, 1984
Summary: We obtain integro-differential equations for the electric and magnetic fields inside a linear, lossy, and anisotropic scatterer, in the frequency domain. The material of the scatterer is characterized by arbitrary values of the elements of the relative permittivity tensor \(\overline{\varepsilon}\), the relative permeability tensor \(\overline{

Electromagnetic radiation in the general theory of relativity. I

Soviet Physics Journal, 1973
The possibilities are investigated for the joint solution of Einstein's and Maxwell's equations for an isotropic electromagnetic field. Three groups of metric forms of space are shown, in which such a solution is permissible.

The arrow of electromagnetic time and the generalized absorber theory

Foundations of Physics, 1983
The problem of the direction of electromagnetic time, i.e., the complete dominance of retarded electromagnetic radiation over advanced radiation in the universe, is considered in the context of a generalized form of the Wheeler-Feynman absorber theory in an open expanding universe with a singularity atT=0.

Generalized static electromagnetic fields in Brans–Dicke theory

Journal of Mathematical Physics, 1979
A general class of static, axially symmetric solutions of the Brans–Dicke–Maxwell equations is obtained under the assumption −r2⋅grr=gtt⋅gφφ⋅gzz These solutions have been subjected to conformal transformation and they are found to be new solutions of the static, axially symmetric Einstein–Maxwell–scalar fields. We have also developed a more general set

A spinor formulation of electromagnetic theory in general relativity

Il Nuovo Cimento, 1964
The spinor formulation of the Maxwell-Lorentz theory that was developed earlier bySachs andSchwebel (2–3) is extended to a generally covariant formalism. The underlying group for electrodynamics is thereby generalized from the proper inhomogeneous Lorentz groupLp to a special topological groupT.

Quasilinear theory of general electromagnetic fluctuations in unmagnetized plasmas

Physics of Plasmas, 2014
The general quasilinear Fokker-Planck kinetic equation for the plasma particle distribution functions in unmagnetized plasmas is derived, making no restrictions on the frequency of the electromagnetic fluctuations. The derived kinetic particle equation complements our earlier study of the general fluctuation's kinetic equation.

A scheme to generalize signal theory and its application to electromagnetics

2009 IEEE Antennas and Propagation Society International Symposium, 2009
The scheme summarized in this work is being applied to generalize the solution to problems described by differential operators with some boundary conditions applying over signals spaces which depend on several dimensions -for instance, in given equation.
