4Ground-penetrating radar — (GPR) is a geophysical method that uses radar pulses to image the subsurface. This non destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from… …
5Impedance matching — In electronics, impedance matching is the practice of designing the input impedance of an electrical load (or the output impedance of its corresponding signal source) to maximize the power transfer and/or minimize reflections from the load.… …
6Ground loop (electricity) — In an electrical system, a ground loop usually refers to a current, generally unwanted, in a conductor connecting two points that are supposed to be at the same potential, often ground, but are actually at different potentials. Ground loops… …
7Ground plane — In electrical engineering, a ground plane is an electrically conductive surface. Radio antenna theory In telecommunication, a ground plane structure or relationship exists between the antenna and another object, where the only structure of the… …
8Ground (electricity) — In electrical engineering, ground or earth may be the reference point in an electrical circuit from which other voltages are measured, or a common return path for electric current, or a direct physical connection to the Earth. A typical earthing… …
9Ground and neutral — For uses of the term ground or earth in electricity but not in the context of mains wiring, see ground (electricity). Since the neutral point of an electrical supply system is often connected to earth ground, ground and neutral are closely… …
