Abstract
Unconventional imaging and focusing properties are obtained when odd p owers of the radial coordinate are present in a radial gradient-index profile. We calculate the transmittance function for this kind of medi um under a paraxial approximation by a quasi-geometrical approach. Lik ewise, we analyze the pupil effect; that is, we evaluate the intensity distribution diffracted by a gradient-index axicon at the image plane .
