quadrupole — A collection of charges such that the potential at a point distance r from their center of mass may be expressed by an infinite series of terms in inverse powers of r. The inverse third power term is the quadrupole potential … Dictionary of automotive terms
Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… … Wikipedia
Quadrupole ion trap — Scheme of a Quadrupole ion trap of classical setup with a particle of positive charge (dark red), surrounded by a cloud of similarly charged particles (light red). The electric field E (blue) is generated by a quadrupole of endcaps (a, positive)… … Wikipedia
Quadrupole — A quadrupole or quadrapole is one of a sequence of configurations of for example electric charge or current, or gravitational mass that can exist in ideal form, but it is usually just part of a multipole expansion of a more complex structure… … Wikipedia
Multipole radiation — is a theoretical framework for the description of electromagnetic or gravitational radiation from time dependent distributions of distant sources. These tools are applied to physical phenomena which occur at a variety of length scales from… … Wikipedia
Axial multipole moments — are a series expansionof the electric potential of acharge distribution localized close to the origin along one Cartesian axis, denoted here as the z axis. However, the axial multipole expansion can also be applied to any potential or field that… … Wikipedia
