They cover effective medium theory, artificial particles: "man-made atoms" or "meta-atoms," homogeneous metamaterials: super crystals, random metamaterials: super noncrystals, inhomogeneous metamaterials: super quasicrystals,
gradient-index inhomogeneous metamaterials, nearly isotropic inhomogeneous metamaterials, and anisotropic inhomogeneous metamaterials.
Made by graded photonic crystal, the
gradient-index lens can lead to high gain and low sidelobes with this lens placed inside a horn antenna [5].

The cloak, designed by Cheng Sun, assistant professor of mechanical engineering at Northwestern's McCormick School of Engineering and Applied Science, uses micro fabricated
gradient-index materials to manipulate the reflection and refraction of light.
Our patented endoGRINS[R]
gradient-index lenses are built into our exclusive line of Hawkeye[R] Rigid Precision Borescopes.
Among the systems covered over the course of 43 chapters are telephoto lenses, eyepieces, afocal optical systems, periscope systems, enlarging and copying lenses, projection lenses, wedge-plate and rotary-prism cameras, optically and mechanically compensated zoom lenses, copy lenses with variable magnification,
gradient-index lenses, spectrographic systems, and diffractive systems.
This employs small optical components such as
gradient-index lenses and mirrors to reflect light around the bend.
It consists of a small laser, a
gradient-index (GRIN) lens, a beamsplitter, and a reference element.
