Design and transformation of three dimensional pupils : diffractive and subwavelength
… Inhomogeneity is discussed in the context of gradient--index media. The additional thin--film wave guidance effect along the third dimension due to fabrication constraints is investigated in detail with the proposal of an all--analytical solution.

Diffraction-based Optical Architectures for Processing One-dimensional Data
… new methods for designing aberration-free gradient index lenses. Parameter sweeps are demonstrated to find lenses within the framework, with minimal dynamic range of refractive index distributions found from two families of aberration-free collimation lenses. As such, the theoretical tools …
