  • Patent number: 9400219
    Abstract: Metallic thermal emitters consisting of two layers of differently structured nickel gratings on a homogeneous nickel layer are fabricated by soft lithography and studied for polarized thermal radiation. A thermal emitter in combination with a sub-wavelength grating shows a high extinction ratio, with a maximum value close to 5, in a wide mid-infrared range from 3.2 to 7.8 ?m, as well as high emissivity up to 0.65 at a wavelength of 3.7 ?m. All measurements show good agreement with theoretical predictions. Numerical simulations reveal that a high electric field exists within the localized air space surrounded by the gratings and the intensified electric-field is only observed for the polarizations perpendicular to the top sub-wavelength grating. This result suggests how the emissivity of a metal can be selectively enhanced at a certain range of wavelengths for a given polarization.

  • Patent number: 8968984
    Abstract: Disclosed is a photosensitive resin composition for an organic insulating layer. More specifically, the photosensitive resin composition is suitable for forming a substrate of a transflective thin film transistor liquid crystal display (TFT-LCD) or a pattern of an interlayer insulating layer by improving remarkably a pattern property with a high taper angle besides improvement of flatness, sensitivity, heat resistance, and transparency. Particularly, the photosensitive resin composition can provide low power dissipation besides a wide viewing angle and high visibility when being applied to a transflective type display. In addition, the photosensitive resin composition can provide a clear screen under natural light without a backlight by maintaining the brightness of a screen and prominent field visibility.
