  • Patent number: 8509578
    Abstract: A method for carrying out electromagnetic cloaking using metamaterial devices requiring anisotropic dielectric permittivity and magnetic permeability may be emulated by specially designed tapered waveguides. This approach leads to low-loss, broadband performance in the visible frequency range, which is difficult to achieve by other means. We apply this technique to electromagnetic cloaking. A broadband, two-dimensional, electromagnetic cloaking is demonstrated in the visible frequency range on a scale ˜100 times the wavelength. Surprisingly, the classic geometry of Newton rings is suited for an experimental demonstration of this effect.

  • Patent number: 8488072
    Abstract: To provide a structure and a manufacturing method which can manufacture, at a low cost and with good yield, a liquid crystal display panel having a lenticular lens and a substrate formed in a unified manner. When forming a lenticular lens onto a mother CF substrate by using a wet etching method, substrates are dipped into an etching solution while being raised up in such a manner that the length direction of slit openings of a mask is aligned with a vertical direction and an area having no mask pattern comes on a bottom side. With this, the residuals generated due to glass impurities can be drained towards the lower side along the lenticular lens shape to be discharged to the flat area, which makes it possible to suppress deterioration in the etching processed shape.

  • Patent number: 8428410
    Abstract: The present invention embraces a multimode optical fiber that includes a central core having an alpha-index profile, an inner cladding, a depressed trench, and an outer cladding (e.g., an outer optical cladding). Typically, the central core's alpha-index profile has a minimum refractive index at the central core's radius that corresponds to a refractive index difference with respect to the outer cladding. The optical fiber achieves reduced bending losses and a high bandwidth with a reduced cladding effect for high-data-rate applications.
