| dc.description.abstract | The propagation of electromagnetic waves in a cold magnetized plasma with ferromagnetic grains (MPFG) in the high frequency domain is studied. The MPFG medium that consists of magnetized electron-ion plasma and ferromagnetic grains is assumed to be a homogeneous anisotropic medium. Its dispersion properties which is controlled by the simultaneous characterization of the permittivity and permeability tensors is investigated theoretically and numerically near the resonance frequency. It is found that MPFG becomes transparent for the waves that cannot propagate in conventional magnetized electron-ion plasma. The refractive index of the waves propagating parallel to the applied magnetic field is found to be negative for the extraordinary wave in certain frequency domain. Moreover, by varying the parameters of the electric subsystem (electron-ion plasma), the nontransparent region for electromagnetic wave propagation can be eliminated. The results obtained show that in a narrow band of the super-high-frequency range near the electron cyclotron frequency, the MPFG medium possesses all the known characteristics of negative refractive index media, which would make it as a viable alternative medium to demonstrate the known and predicted peculiar properties of media having negative index of refraction | en_US |
