摘要： An electromagnetic interference (EMI) shielding material includes a matrix of a dielectric or partially conducting polymer, such as foamed polystyrene, with carbon nanotubes or other nanostructures dispersed therein in sufficient concentration to make the material electrically conducting. The composite is formed by dispersing the nanotube material in a solvent in which the dielectric or partially conducting polymer is soluble and mixing the resulting suspension with the dielectric or partially conducting polymer. A foaming agent can be added to produce a lightweight foamed material. An organometallic compound can be added to enhance the conductivity further by decomposition into a metal phase.

摘要： A method is disclosed for making an optical device which is adapted to diffract an incident beam of radiation to form a plurality of discrete diffracted beams of different orders. The optical device comprises two diffraction gratings which are supported on a substrate and are separated from each other by a thin film. In order to obtain the advantages of a doubly-periodic structure, the thickness of the thin film between the two gratings is very accurately controlled to be on the order of the wavelength of the incident beam of radiation.

摘要： A method for the replication of a textured surface of a master is disclosed, in which the textured surface of the master is comprised of micron-scale cones having nano- or micro-scale surface features. Alternatively, the master may be comprised of micron-scale structures, nano-scale structures, and micron scale structures having nano-scale surface features. Replication can be achieved through a molding or embossing technique. Using these technique, the textured surface of the master is faithfully replicated onto the surface of the replica. A number of representative materials and additional processing steps are also disclosed. The replicated texture exhibits many useful properties, including enhanced hydrophobicity and reduced light reflection properties, making the disclosed method a simple and attractive alternative to existing texturing techniques.

摘要： The surface of a material is textured and by exposing the surface to pulses from an ultrafast laser. The laser treatment causes pillars to form on the treated surface. These pillars provide for greater light absorption. Texturing and crystallization can be carried out as a single step process. The crystallization of the material provides for higher electric conductivity and changes in optical and electronic properties of the material. The method may be performed in vacuum or a gaseous environment. The gaseous environment may aid in texturing and/or modifying physical and chemical properties of the surfaces. This method may be used on various material surfaces, such as semiconductors, metals and their alloys, ceramics, polymers, glasses, composites, as well as crystalline, nanocrystalline, polycrystalline, microcrystalline, and amorphous phases.

摘要： A ferroelectric light frequency doubler device has a surface coating on one surface of an initially uniformly poled ferroelectric crystal, the surface coating on the one surface being exposed to a scanning electron beam so as to form a spatially periodically alternating polarity domain structure in the crystal. The surface coating can be of an inorganic material or it can be of a polymeric organic material. The surface coating can be adapted to be patterned to form an optical grating in registrative alignment with the spatially periodically alternating polarity domain structure when such optical grating is desired. Alternatively, the surface coating may remain on the device as a protective coating, or it may be removed upon formation of the alternating polarity domain structure in the crystal. When the surface coating is adapted to be responsive to the scanning electron beam, the spatially periodically alternating domains in the ferroelectric crystal and a latent optical grating pattern in the surface coating are established at the same time by the electron beam. The latent optical grating pattern can be formed into an optical grating during a subsequent pattern development step.

摘要： A surface relief reflection diffraction grating is used as a wavelength compensating element for a diffraction grating coupler. The changes in wavelength are compensated for by adjusting the parameters of the reflection diffraction grating so that the dispersion of the reflection diffraction grating is generally equal and opposite to the dispersion of the diffraction grating coupler. The technique has been shown to permit the range of wavelengths which can coupled with the diffraction grating coupler to be extended from 0.7 nm to 17 nm. The lateral shift has an important contribution and can be limiting factor in wavelength compensation.
