Abstract
|
We study the propagation of electromagnetic
waves (EMWs) in both isotropic and anisotropic
ferromagnetic material media. As the EMW
propagates through linear charge-free isotropic
and anisotropic ferromagnetic media, it is found
that the magnetic field and the magnetic
induction components of the EMW and the
magnetization excitations of the medium are in
the form of solitons. However, the
electromagnetic soliton gets damped and
decelerates in the case of a charged medium. In
the case of a charge-free nonlinear ferromagnetic
medium we obtain results similar to those for the
linear case.
