The general solution presented here yields smooth, continuous, and monotonic refractive-index profiles for Luneburg-Morgan lenses with a boundary index of N > 1. The new formula incorporates an original apparent-immersing method as well as the continuous-deflection-function concept recently developed by one of the authors for the description of waveguide lenses.
