The focus of this report is the peculiarities of electromagnetic wave propagation in magnetic metamaterials
with a periodic array of two-dimensional (2D) electronic gas layers. A model system is considered which
consists of alternating layers of a magnetic insulator and nanoscale metallic layers or GaAs-AlGaAs-type
semiconductor bilayers with 2D electronic plasma. In the presence of a strong external magnetic field
perpendicular to the plane of the layers, the Landau quantization of the electron motion and confinement of the
electrons within 2D layers lead to the realization of the integer quantum Hall effect. Assuming that a unit cell
dimension of the structure is much smaller than the wavelength of interest and using expressions for the effective
permittivity and permeability tensors of the system, the dispersion relations and behavior of refracted
electromagnetic waves are studied at an arbitrary angle of incidence with respect to the magnetic field. It is
shown that when the wave is incident on the top surface of the structure, the negative refraction is impossible.
Despite of that, the medium exhibits a propagation of a backward wave with wavefront normal directed toward
the refracting interface. In addition, the frequency regions of existence for the backward waves can be tuned by
applied magnetic field. The effects of the quantization of 2D electron dynamics are examined
