摘要
This manuscript investigates a generalized problem for electromagnetic wave propagation in graphene-wrapped circular waveguides filled with magnetized plasma. Kubo formulism is used for graphene conductivity and impedance boundary conditions are applied to solve the numerical problem. The behavior of the dispersion curves is examined and evaluated computationally. The presented results demonstrate that graphene conductivity has a strong influence on electromagnetic wave propagation for the proposed design. The normalized propagation constant and attenuation phase constant are studied under different values for the operating frequency, radius, plasma frequency, and cyclotron frequency. The presented results may find applications in communication at THz frequency regime, optical sensing and cancer treatment at the specific plasma frequency using magnetized plasma.
