Dipoles

Some articles on dipoles, dipole:

Antiferroelectricity
... an ordered (crystalline) array of electric dipoles (from the ions and electrons in the material), but with adjacent dipoles oriented in opposite (antiparallel) directions (the dipoles of each orientation form ... with a ferroelectric, in which the dipoles all point in the same direction ... spontaneous polarization is zero, since the adjacent dipoles cancel each other out ...
HRS Antenna - Nomenclature
... First symbol Indicates the orientation of the dipoles in the array ... come three numbers "x/y/z" where 'x' (an integer) is the number of dipoles counting horizontally ... 'y' (an integer) is the number of dipoles counting vertically and 'z' (a decimal fraction) is the height above ground (in wavelengths) of the lowest row of dipoles in the array ...
Discrete Dipole Approximation - Basic Concepts
... The points acquire dipole moments in response to the local electric field ... The dipoles of course interact with one another via their electric fields, so the DDA is also sometimes referred to as the coupled dipole approximation ... For a finite array of point dipoles the scattering problem may be solved exactly, so the only approximation that is present in the DDA is the replacement of the continuum target by an array of N-point ...
Magnetic Dipole–dipole Interaction
... Magnetic dipoledipole interaction, also called dipolar coupling, refers to the direct interaction between two magnetic dipoles ... to the line joining the centers of the two dipoles ... rjk is the distance between two dipoles, mk and mj ...
1,3-Dipolar Cycloaddition - Mechanistic Overview - 1,3-Dipole
... A 1,3-dipole is a chemical species that can be represented as either an allyl-type or a propargyl/allenyl-type zwitterionic octet/sextet structures ... Both types of 1,3-dipoles share four electrons in the π-system over three atoms ... There are a total of 12 allyl-type and 6 propagyl/allenyl-type second-row 1,3-dipoles (which consist of carbon, nitrogen and oxygen centers) ...
