  2. Waveguide - Wikipedia

    en.wikipedia.org/wiki/Waveguide

    Electric field Ex component of the TE31 mode inside an x-band hollow metal waveguide. A waveguide is a structure that guides waves by restricting the transmission of energy to one direction. Common types of waveguides include acoustic waveguides which direct sound, optical waveguides which direct light, and radio-frequency waveguides which ...

  3. Common ethanol fuel mixtures - Wikipedia

    en.wikipedia.org/wiki/Common_ethanol_fuel_mixtures

    Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low-ethanol blends are typically from E5 to E25, although internationally the most common use of the term refers to the E10 blend. Blends of E10 or less are used in more than ...

  4. Waveguide (radio frequency) - Wikipedia

    en.wikipedia.org/wiki/Waveguide_(radio_frequency)

    In radio-frequency engineering and communications engineering, waveguide is a hollow metal pipe used to carry radio waves. This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave radio links.

  5. Sheet metal - Wikipedia

    en.wikipedia.org/wiki/Sheet_metal

    Sheet metal is metal formed into thin, flat pieces, usually by an industrial process. Thicknesses can vary significantly; extremely thin sheets are considered foil or leaf, and pieces thicker than 6 mm (0.25 in) are considered plate, such as plate steel, a class of structural steel . Sheet metal is available in flat pieces or coiled strips.

  6. Guided-mode resonance - Wikipedia

    en.wikipedia.org/wiki/Guided-mode_resonance

    Guided-mode resonance. Guided-mode resonance or waveguide-mode resonance is a phenomenon wherein the guided modes of an optical waveguide can be excited and simultaneously extracted by the introduction of a phase-matching element, such as a diffraction grating or prism. Such guided modes are also called "leaky modes", as they do not remain ...

  7. Waveguide (optics) - Wikipedia

    en.wikipedia.org/wiki/Waveguide_(optics)

    Waveguide (optics) An optical waveguide is a physical structure that guides electromagnetic waves in the optical spectrum. Common types of optical waveguides include optical fiber waveguides, transparent dielectric waveguides made of plastic and glass, liquid light guides, and liquid waveguides. Optical waveguides are used as components in ...

  8. Drawing (manufacturing) - Wikipedia

    en.wikipedia.org/wiki/Drawing_(manufacturing)

    Drawing is a manufacturing process that uses tensile forces to elongate metal, glass, or plastic. As the material is drawn (pulled), it stretches and becomes thinner, achieving a desired shape and thickness. Drawing is classified into two types: sheet metal drawing and wire, bar, and tube drawing. Sheet metal drawing is defined as a plastic ...

  9. Zero-mode waveguide - Wikipedia

    en.wikipedia.org/wiki/Zero-mode_waveguide

    A zero-mode waveguide is an optical waveguide that guides light energy into a volume that is small in all dimensions compared to the wavelength of the light. Zero-mode waveguides have been developed for rapid parallel sensing of zeptolitre sample volumes, as applied to gene sequencing , by Pacific Biosciences (previously named Nanofluidics, Inc ...
