Axial propagation in a magnetic-dielectric cholesteric medium

Abstract
The existence of an exact solution for axial propagation in a dielectric cholesteric medium has been often remarked upon. Here, we obtain the exact solution for axial propagation in a magnetic-dielectric cholesteric medium, using the 4 × 4 matrix method of optics. Our solution procedure also enables us to identify the specific features that make axial propagation in cholesteric media remarkable in having an analytical solution.
