An analysis of guided modes in graphene waveguides in the presence of magnetic-electric barrier is presented. The graphene waveguide is controlled by the gate voltages and the magnetic field by depositing two parallel ferromagnets on a dielectric layer. Both in the classical motion and Klein tunneling cases, the fundamental modes exist with the applied magnetic field. The electron wave propagation can be modulated in two different ways by changing the magnetic intensity or the incident energy. We hope that these characteristics can provide potential applications in the graphene-based waveguide devices.
