  Electrodynamic properties of the graphene - magnetic semiconductor - graphene
sandwich-structure have been investigated theoretically with taking into
account the dissipation processes. Influence of graphene layers on
electromagnetic waves propagation in graphene - semi-infinte magnetic
semiconductor and graphene - magnetic semiconductor - graphene
sandwich-structure has been analyzed. Frequency and field dependences of the
reflectance, transmittance and absorbtance of electromagnetic waves by such
structure have been calculated. The size effects associated with the thickness
of the structure have been analyzed. The possibility of efficient control of
electrodynamic properties of graphene - magnetic semiconductor - graphene
sandwich structure by an external magnetic field has been shown.
