摘要

Fibers are today not only important as waveguides for long distance transmission of optical signals, but also in circuits as special phase filters or reflectors. Therefore, in this paper the analysis of a general class of fiber structures will be described. The material may show anisotropic behavior. The formulation in this paper is given in such a way that generalized transmission line equations are obtained in cylindrical coordinates. The analytical solution should be obtained in the propagation direction of the wave. General impedance/admittance and field transformation formulas will be derived which allow an accurate analysis of the devices. Furthermore, based on the generalized transmission line equations a novel BPM algorithm in cylindrical coordinate system will be proposed.
