Abstract

Electromagnetic behavior of twisted clad optical fibers is investigated under the situation of sheath helix of perfect electromagnetic (PEMC) conductor introduced at the core-clad interface. The eigenvalue equation for the structure is deduced by applying suitable boundary conditions, and the dispersion behavior of the fiber is analyzed considering the cases of non-dispersive as well as dispersive core with the sustainment of a few low-order modes. The effect on dispersion properties is observed due to alterations in the pitch angle of helical twists as well as the admittance value of the PEMC material. It has been found that the pitch angle and the admittance values can be properly adjusted to attain the degenerate properties of modes which would find many applications in optics industry.
