Inverse-square law — In physics, an inverse square law is any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. Areas of application In particular the… … Wikipedia
Field emission — (FE) is the emission of electrons from the surface of a condensed phase into another phase due to the presence of high electric fields. In this phenomenon, electrons with energies below the Fermi level tunnel through the potential barrier at the… … Wikipedia
Inverse synthetic aperture radar — (ISAR) is a technique to generate a two dimensional high resolution image of a target.In situations where other radars display only a single unidentifiable bright moving pixel, the ISAR image is often adequate to discriminate between various… … Wikipedia
Inverse problem — An inverse problem is a general framework that is used to convert observed measurements into information about a physical object or system that we are interested in. For example, if we have measurements of the Earth s gravity field, then we might … 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
Intermediate-field region — Intermediate field region: For an antenna, the transition region lying between the near field region and the far field region in which the field strength of an electromagnetic wave is dependent upon the inverse distance, inverse square of the… … Wikipedia
Depth of field — The area within the depth of field appears sharp, while the areas in front of and beyond the depth of field appear blurry … 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
Hyperfocal distance — In optics and photography, hyperfocal distance is a distance beyond which all objects can be brought into an acceptable focus. There are two commonly used definitions of hyperfocal distance , leading to values that differ only slightly:The first… … Wikipedia
Magnetic field — This article is about a scientific description of the magnetic influence of an electric current or magnetic material. For the physics of magnetic materials, see magnetism. For information about objects that create magnetic fields, see magnet. For … Wikipedia
Near Field Magnetic Induction Communication System — A Near Field Magnetic Induction Communication System is a short range wireless physical layer that communicates by coupling a tight, low power, non propagating magnetic field between devices. The concept is for a transmitter coil in one device to … Wikipedia
