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.

  3. A similar concept of design was published slightly earlier by G. Toraldo di Francia, “Mathematical problem of the concentric stigmatic optical system,” Ann. Mat. (Italy) 44, 35–44 (1957) (in Italian). The formulation presented by Morgan is more general, however, and better known to the international optical community.
  4. Another possibility is to assume a certain particular form of the outer-shell, refractive-index distribution for A ≤ p ≤ N, but this coincides with the concept of Morgan and is associated with known disadvantages (see Section 1).
