In the paper, the known possibility to consider the (vacuum)
Maxwell equations in a curved space-time as Maxwell equations in
flat space-time (Mandel'stam L.I., Tamm I.E. [1,2]) but taken in
an effective media the properties of which are determined by
metrical structure of the initial curved model
is studied.
Metrical structure of the curved space-time generates the "material equations"
for electromagnetic fields:
the form of four symmetrical "matherial"
tensors
is found explicitly for general case of an arbitrary Riemannian space-time geometry
:
Several, the most simple examples are specified in detail: it is given geometrical modeling of the anisotropic media (magnetic crystals)
and the geometrical modeling of a uniform media in
moving reference frame in the background of Minkowsky
electrodynmamics -- the latter is realized trough the use of a
non-diagonal metrical tensor determined by 4-vector velocity of
the moving uniform media
The main peculiarity of the geometrical generating for
effective electromagnetic medias characteristics consists in the
following: four tensors
are not independent and
obey some additional constraints between them.
Key words:
Maxwell equations, curved space-time
