  The transmission of electromagnetic wave through the planar chiral structure,
loaded with the gyrotropic medium on the longitudinal magnetic field is
studied. The frequency dependence of the metamaterial resonance and the angle
of rotation of the polarization plane are obtained. We define both
theoretically and experimentally the range of frequencies and magnetic fields,
where the angle of polarization plane rotation for the metamaterial is
essentially higher than for a single ferrite slab.
