The Magnetic Current Component in the Conductivity Tensor

TL;DR

This paper proposes a new magnetic component in the electrical conductivity tensor, derived from electromagnetic theory, which influences wave propagation in various media and requires specific experimental conditions for observation.

Contribution

It introduces a novel magnetic component in the conductivity tensor and analyzes its implications for wave propagation and experimental detection.

Findings

The new component appears at the second order of spatial dispersion.

Optical spatial and time dispersion effects are necessary for observing this component.

A two-wave propagation effect related to this component is predicted.

Abstract

The theory of electromagnetic in nature new component of electrical current is suggested. In classical physics approximations for the cases of the free electron plasmas in semi-conductive media, the atom or molecular electrons of liquids and amorphous or polycrystalline solid states medias, tensors of conductivity are calculated. It is shown that the resolution of the additional members of the tensors of conductivity in degrees of the spatial dispersion parameter the series begins minus two degree this parameter, not the only conventional null degree in beginning takes place. The joined optical spatial and time dispersion effects are to be needed for the experimental observation this non-conventional component of the electrical current. Some discussion of this problem is given. In particular, the two-wave propagation effect predicted is discussed.
