Isotope separation — is the process of concentrating specific isotopes of a chemical element by removing other isotopes, for example separating natural uranium into enriched uranium and depleted uranium. This is a crucial process in the manufacture of uranium fuel… … Wikipedia
Mast radiator — A typical mast radiator in Chapel Hill, North Carolina. The high RF voltage on the mast can deliver a dangerous electrical shock to anyone touching it, so the base is surrounded by a fence to prevent access … Wikipedia

Polarizer — For the photographic filter, see Polarizing filter (Photography). A polarizing filter cuts down the reflections (top) and made it possible to see the photographer through the glass at roughly Brewster s angle although reflections off the back… … Wikipedia
Near and far field — This article is about the electromagnetic concept. For the mathematical, see Near field (mathematics). Antenna field regions for antennas that are shorter than the wavelength of the radiation they emit, such as the whip antenna of a citizen s… … Wikipedia
Fabry-Pérot interferometer — In optics, a Fabry Pérot interferometer or etalon is typically made of a transparent plate with two reflecting surfaces, or two parallel highly reflecting mirrors. (Technically the former is an etalon and the latter is an interferometer, but the… … Wikipedia
Fabry–Pérot interferometer — Étalon redirects here. For the commune in Somme, France, see Étalon, Somme. Interference fringes, showing fine structure, from a Fabry–Pérot etalon. The source is a cooled deuterium lamp. In optics, a Fabry–Pérot interferometer or etalon is typic … Wikipedia
History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… … Wikipedia
