Abstract
Light transmission through a gradient-index medium, whose refractive-i ndex profile can be represented by a one-dimensional hyperbolic secant function, is analyzed by a wave-optics approach. An asymptotic expres sion of the corresponding optical propagator (the Green's function) in this medium is evaluated in a such a way that nonparaxial propagation can be studied. Thus optical transformations such as focusing and col limation are obtained, and the pupil effect (diffractive effect) is sh own.
