Description
Summary:Theoretical analysis of the electromagnetic wave propagation in circular waveguides with a chiroplasma core coated with a perfect electromagnetic conductor (PEMC) is presented. The presented formulations and analysis are general for any perfect electric, perfect magnetic, or perfect electromagnetic conductor (PEMC) waveguides filled with any general anisotropic/isotropic metamaterial including plasma. The characteristic equation for the modes in this waveguide is obtained, and the behavior of the dispersion curves and the power flux are examined and evaluated numerically. The results demonstrate that the behavior of the power flux transported in the guide, in magnitude and orientation, is highly determined by the chirality parameter and the plasma and cyclotron frequencies. The mode cutoff frequencies are sensitive to the variations in the filling material and chirality parameters and likewise affected by the variations in the PEMC admittance parameter. Key Points Energy flux distribution in chiroplasma PEMC waveguide may be obtained The dispersion diagram, cutoff frequencies, and the propagating modes The chirality, plasma, and cyclotron frequency effects on the energy flux
