Free space — In classical physics, free space is a concept of electromagnetic theory, corresponding to a theoretically perfect vacuum, and sometimes referred to as the vacuum of free space. The definitions of the ampere and meter SI units are based upon… … Wikipedia
Free-space path loss — In telecommunication, free space path loss (FSPL) is the loss in signal strength of an electromagnetic wave that would result from a line of sight path through free space, with no obstacles nearby to cause reflection or diffraction. It does not… … Wikipedia
Impedance of free space — The impedance of free space, Z0, is a physical constant relating the magnitudes of the electric and magnetic fields of electromagnetic radiation travelling through free space. That is, Z0 = |E|/|H|, where |E| is the electric field strength and… … Wikipedia
Free electron model — In three dimensions, the density of states of a gas of fermions is proportional to the square root of the kinetic energy of the particles. In solid state physics, the free electron model is a simple model for the behaviour of valence electrons in … Wikipedia
Wave function — Not to be confused with the related concept of the Wave equation Some trajectories of a harmonic oscillator (a ball attached to a spring) in classical mechanics (A B) and quantum mechanics (C H). In quantum mechanics (C H), the ball has a wave… … Wikipedia
Wave impedance — The wave impedance of an electromagnetic wave, is the ratio of the transverse components of the electric and magnetic fields (the transverse components being those at right angles to the direction of propagation). For a transverse electric… … Wikipedia
Free particle — In physics, a free particle is a particle that, in some sense, is not bound. In classical physics, this means the particle is present in a field free space. Classical Free Particle The classical free particle is characterized simply by a fixed… … Wikipedia
space — 1. noun /speɪs/ a) The intervening contents of a volume. If it be only a Single Letter or two that drops, he thruſts the end of his Bodkin between every Letter of that Word, till he comes to a Space: and then perhaps by forcing thoſe Letters… … Wiktionary
Wave field synthesis — (WFS) is a spatial audio rendering technique, characterized by creation of virtual acoustic environments. It produces artificial wave fronts synthesized by a large number of individually driven speakers. Such wave fronts seem to originate from a… … Wikipedia
