  • Patent number: 7808716
    Abstract: Negative refraction in photonic crystals and diffraction grating is used to design plano-concave lenses to focus plane waves. Microwave experiments are carried out to demonstrate negative refraction and the performance of these lenses. Demonstration of negative refraction of visible light is also performed for the grism. These lenses can be used in optical circuits, astronomical applications, etc.
    Type: Grant
