Electromagnetic Waves Guided by an Array of Parallel Gyrotropic Cylinders

Abstract

The propagation of electromagnetic waves guided by an array of parallel identical cylinders that are filled with a gyrotropic medium and placed in free space is studied. It is assumed that the gyrotropic medium is a cold magnetoplasma and the cylinders are aligned with an external static magnetic field. It is shown that a guiding structure consisting of several identical gyrotropic cylinders supports the propagation of a greater number of modes than a single-cylinder waveguide. Conditions are found under which the mutual influence of the cylinders can be neglected when calculating the properties of the guided modes.
