  2. Delta Field (Niger Delta) - Wikipedia

    en.wikipedia.org/wiki/Delta_Field_(Niger_Delta)

    Image from USGS Open-File Report 99-50-H [2] The Delta Field is located offshore from Nigeria on Oil Mining Leases (OML) 49 and 95. [3] This is located within the Niger Delta Basin and sits in 12 feet of water. In 1965, the Delta 1 well was completed and the Delta Field opened in 1968 for production. [3]

    PPSh-45: A late war variant of PPSh-41, featuring only full auto and using early PPSh-41 production tangent sights. It had a foldable stock that could also be used as a grip, and had no wood parts. It had a foldable stock that could also be used as a grip, and had no wood parts.

  4. Propagation constant - Wikipedia

    en.wikipedia.org/wiki/Propagation_constant

    The propagation constant of a sinusoidal electromagnetic wave is a measure of the change undergone by the amplitude and phase of the wave as it propagates in a given direction. The quantity being measured can be the voltage , the current in a circuit , or a field vector such as electric field strength or flux density .

  5. Tangent - Wikipedia

    en.wikipedia.org/wiki/Tangent

    The tangent plane to a surface at a given point p is defined in an analogous way to the tangent line in the case of curves. It is the best approximation of the surface by a plane at p , and can be obtained as the limiting position of the planes passing through 3 distinct points on the surface close to p as these points converge to p .

  8. Line-of-sight propagation - Wikipedia

    en.wikipedia.org/wiki/Line-of-sight_propagation

    The presence of objects not in the direct line-of-sight can cause diffraction effects that disrupt radio transmissions. For the best propagation, a volume known as the first Fresnel zone should be free of obstructions. Reflected radiation from the surface of the surrounding ground or salt water can also either cancel out or enhance the direct ...

  9. Surface acoustic wave - Wikipedia

    en.wikipedia.org/wiki/Surface_acoustic_wave

    Experimental image of surface acoustic waves on a crystal of tellurium oxide [1]. A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material exhibiting elasticity, with an amplitude that typically decays exponentially with depth into the material, such that they are confined to a depth of about one wavelength.
