  2. Planar lightwave circuit interferometer - Wikipedia

    en.wikipedia.org/wiki/Planar_lightwave_circuit...

    Planar lightwave circuits are either optical integrated circuits (ICs) or optical circuit boards made using the same manufacturing techniques as their electronic counterparts, using optical waveguides to route photons the same way that metal traces are used to route electrons in electronic ICs and circuit boards.

  3. Planar process - Wikipedia

    en.wikipedia.org/wiki/Planar_process

    The planar process is a manufacturing process used in the semiconductor industry to build individual components of a transistor, and in turn, connect those transistors together. It is the primary process by which silicon integrated circuit chips are built, and it is the most commonly used method of producing junctions during the manufacture of ...

  4. Magnepan - Wikipedia

    en.wikipedia.org/wiki/Magnepan

    Magnepan has used several different technologies in constructing their magnetostatic speakers.All Magnepan speakers are based on flexible ferrite magnet strips (like refrigerator magnets), 0.060" (1.5 mm) thick, typically cut to either 1/4" (6 mm) wide (mid-bass) or 1/8" (3 mm) wide (tweeters) and more or less the length of the speaker.

    "Substrate" might be defined. "the planar format fits in well with the manufacturing methods" could become "the planar format is easy to manufacture", etc. The Modes section could be made more accessible with some diagrams showing some modes, especially if those mode are superimposed with the planar circuit geometry. Those are my first impressions.

  6. Planar Systems - Wikipedia

    en.wikipedia.org/wiki/Planar_Systems

    Planar Systems, Inc. is an American digital display manufacturing corporation with a facility in Hillsboro, Oregon. Founded in 1983 as a spin-off from Tektronix , it was the first U.S. manufacturer of electroluminescent (EL) digital displays.

  7. Coplanar waveguide - Wikipedia

    en.wikipedia.org/wiki/Coplanar_waveguide

    Coplanar waveguides play an important role in the field of solid state quantum computing, e.g. for the coupling of microwave photons to a superconducting qubit.In particular the research field of circuit quantum electrodynamics was initiated with coplanar waveguide resonators as crucial elements that allow for high field strength and thus strong coupling to a superconducting qubit by confining ...

  8. Shocked quartz - Wikipedia

    en.wikipedia.org/wiki/Shocked_quartz

    Shocked quartz was discovered following underground nuclear weapons testing, which generated the intense pressures required to alter the quartz lattice. Eugene Shoemaker showed that shocked quartz is also found inside craters created by meteor impact, such as the Barringer Crater and Chicxulub crater. [1]

    In contrast, the extra stability of the 7p 1/2 electrons in tennessine are predicted to make TsF 3 trigonal planar, unlike the T-shaped geometry observed for IF 3 and predicted for AtF 3; [39] similarly, OgF 4 should have a tetrahedral geometry, while XeF 4 has a square planar geometry and RnF 4 is predicted to have the same.
