Graded Photonic Crystals for Luneburg Lens
The Luneburg lens is a radially graded index refracting structure that forms geometrical images of two given concentric spheres on each other. This remarkable property of the Luneburg lens makes it very attractive for various domains of frequency and applications. However, its continuous gradient in...

| Summary: | The Luneburg lens is a radially graded index refracting structure that forms geometrical images of two given concentric spheres on each other. This remarkable property of the Luneburg lens makes it very attractive for various domains of frequency and applications. However, its continuous gradient index is difficult to realize in practice. Herein, we propose the use of graded photonic crystals to attain the radially graded index of the Luneburg lens and show that graded photonic crystals with fitted gradient of filling factor exhibit the properties of the Luneburg lens. |
