Abstract

This work presents electromagnetic wave propagation in the elliptical waveguides filled with chiroplasma core and an outer perfect electromagnetic conductor boundary. The electromagnetic fields were theoretically examined. The hybrid modes’ dispersion relations and power flux density were calculated considering appropriate boundary conditions, and their behaviors were numerically and graphically studied. The effects of the plasma frequency, the cyclotron frequency, the chirality parameter, and the perfect electromagnetic conductor admittance parameter were investigated for the cutoff frequency. Different modes were considered, and the dispersion relation was plotted and studied for each case. It was shown that the cutoff frequency changes with the change of various parameters such as the plasma and cyclotron frequencies, the chirality parameter, and the perfect electromagnetic conductor admittance parameter. In addition, it was shown that for the considered mode, when the plasma or cyclotron frequencies increase, the values of correspond cutoff frequencies have higher or lower values, respectively. Higher values of the perfect electromagnetic conductor admittance parameter or the chirality admittance parameter yield lower or higher cutoff frequencies of the modes, respectively.
