Abstract
A new method intended for the calculation of eigenmodes and leaky modes in layered dielectric and metal-dielectric waveguide structures possessing azimuthal symmetry is described. The proposed method generalizes the approach developed by Golant [1] for the analysis of planar layered structures. The numerical procedure is stable in application to the systems with wave tunneling or decay (instability) in radial directions. Possibilities of the proposed method are demonstrated in calculations of the Bragg optical fibers of various types.
