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
Near Field Communication — or NFC, is a short range high frequency wireless communication technology which enables the exchange of data between devices over about a 10 centimetre (around 4 inches) distance.Fact|date=July 2008 The technology is a simple extension of the ISO … Wikipedia
Near field communication — An NFC enabled mobile phone interacting with a SmartPoster Near field communication, or NFC, allows for simplified transactions, data exchange, and wireless connections between two devices in proximity to each other, usually by no more than a few … Wikipedia
Field-effect transistor — FET redirects here. For other uses, see FET (disambiguation). High power N channel field effect transistor The field effect transistor (FET) is a transistor that relies on an electric field to control the shape and hence the conductivity of a… … Wikipedia
geomagnetic field — Magnetic field associated with the Earth. It is essentially dipolar (i.e., it has two poles, the northern and southern magnetic poles) on the Earth s surface. Away from the surface, the field becomes distorted. Most geomagnetists explain the… … Universalium
Scalar field theory (pseudoscience) — For the quantum mechanical scalar field theory which is a field theory of spinless particles, see Scalar field theory Scalar field theory (SFT) is a set of theories in a model which posits that there is a basic mechanism that produces the… … Wikipedia
Air Motion Transformer — The Air Motion Transformer (AMT) is a loudspeaker mechanism, or audio transducer, invented by Dr. Oskar Heil. It operates on a different principle than both electrodynamic and electrostatic speaker drivers. The AMT moves air in an augmented, semi … Wikipedia
Wireless energy transfer — or wireless power is the transmission of electrical energy from a power source to an electrical load without artificial interconnecting conductors. Wireless transmission is useful in cases where interconnecting wires are inconvenient, hazardous,… … Wikipedia
