THE VACUUM PERMITTIVITY AND PERMEABILITY TENSORS IN THE PRESENCE OF THE ELECTROMAGNETIC FIELD

Abstract

In this paper we deduce the expressions of the vacuum permittivity and permeability tensors components induced by the electromagnetic background radiation. To achieve this goal we start with the expressions of these tensors modified by an electromagnetic field obtained by Euler and Kockel. These relations are particularized for: plane polarized electromagnetic wave, electromagnetic wave with a certain direction and a monochromatic background wave. In the presence of electromagnetic waves the vacuum is inhomogeneous and anisotropic. In the presence of background of monochromatic electromagnetic waves the vacuum is homogeneous and isotropic.
