ABSTRACT: The
consistent physic-mathematical model of propagation of an electromagnetic wave
in a heterogeneous medium is constructed using the generalized wave equation
and the Dirichlet theorem. Twelve conditions at the interfaces of adjacent
media are obtained and justified without using a surface charge and surface
current in explicit form. The conditions are fulfilled automatically in each
section of counting schemes for calculations. A consistent physicomathematical
model of interaction of nonstationary electric and thermal fields in a layered
medium with allowance or mass transfer is constructed. The model is based on
the methods of thermodynamics and on the equations of an electromagnetic field
and is formulated without explicit separation of the charge carriers and the
charge of an electric double layer. The influence of a slowly moving medium on
the electromagnetic wave propagation is considered. The calculation results
show the absence of the influence of the medium’s motion on the phase shift of
waves, which is consistent with experimental data.
