%X The ray propagation and paraxial image characteristics of a taper-like GRIN fiber is studied in this paper. The ray paths in this taper-like GRIN fiber are oscillatory but variable in amplitude and period. Based on the approximate analytical solutions for ray path equations, the Gaussian optics formulae are derived, and their applicability is also discussed. We finally conclude that the optiacal characteristics of the taper-like GRIN fiber are quite similar to those of the conical GRIN fiber and that they have great potential uses as the important new imaging elements of microoptics and laser devices.
