Characteristics of guided modes in chiroplasma circular waveguides in magnetized plasma

摘要

Theoretical analysis of the electromagnetic wave propagation in circular waveguides with a chiroplasma core and a cladding region filled with an anisotropic plasma medium is presented. The cladding region is assumed to be infinitely extended with an external applied magnetic field oriented along the direction of propagation in the waveguide. The characteristic equation for the modes in this waveguide is obtained. The behavior of the energy flux and the dispersion curves are examined and evaluated computationally. The results demonstrate that the behavior of the energy flux transported in the guide in magnitude and orientation is highly affected by the cyclotron and the plasma frequencies in both regions. The modes' cutoff frequencies are sensitive to the variations in the chirality and the plasma frequency of both regions. (C) 2015 Optical Society of America
