For the sake of clarifying the characteristics of cylindrical travelling wave and step index fiber, the modified zero order Hankel function, which is an approximate harmonic complex function without singularity, is recommended as the eigen function of cylindrical travelling wave in homogeneous dielectric. As the modified zero order Neumann function avoids the singularity in the origin of coordinate, and the concept of the essence of mode field of fiber is engaged, both of zero order Bessel function and modified zero order Neumann function are recommend as the eigen functions of axial electric or magnetic component in the core layer of step index fiber. Then, the analysing method of vector mode of fiber is used for reference, a new eigen equation of step index fiber is recommended. These may provide a new method for analyzing the characteristics of cylindrical travelling wave and step index fiber.
