Exempel på hur du använder DIPOLES i en mening

• Both dipoles and quarter-wavelength monopoles have an omnidirectional radiation pattern in free space when oriented vertically; they radiate equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis.
• Fluorine is more electronegative than nitrogen and the polarity of the N-F bonds is opposite to that of the N-H bonds in ammonia, so that the dipole due to the lone pair opposes the N-F bond dipoles, resulting in a low molecular dipole moment.
• All dipoles are electrically equivalent to two monopoles mounted end-to-end and fed with opposite phases, with the ground plane between them made virtual by the opposing monopole.
• An applied magnetic field can flip the magnetic dipoles that make up the material causing both paramagnetism and ferromagnetism.
• The type of antenna used for cellular base stations (vertical white rectangles in pictures), called a sector antenna, usually consists of a vertical collinear array of dipoles.
• This reflects the fact that the dipoles in the material cannot respond instantaneously to the applied field, and causality considerations lead to the Kramers–Kronig relations.
• Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it.
• Water comprises 70% of the brain, and quantum brain dynamics (QBD) proposes that the electric dipoles of the water molecules constitute a quantum field, referred to as the cortical field, with corticons as the quanta of the field.
• Initial versions of AI radar were metric-wavelength, the antennas being arrow-shaped or dipoles, later centimetric versions used a rotating paraboloid aerial carried under a streamlined nose radome.
• The mass quadrupole moment is also important in general relativity because, if it changes in time, it can produce gravitational radiation, similar to the electromagnetic radiation produced by oscillating electric or magnetic dipoles and higher multipoles.
• These deflections create a change in acceleration which in turn produces emission of broad synchrotron radiation tangent to the curve, much like that of a bending magnet, but the intensity is higher due to the contribution of many magnetic dipoles in the wiggler.
• The electrostatic interaction model of ions in solids has thus been extended to a point multipole concept that also includes higher multipole moments like dipoles, quadrupoles etc.
• Halos pick up less nearby electrical spark interference than monopoles and dipoles – ignition noise from vehicles for example.
• Since vertical halfwave dipoles must have their center raised at least a quarter wave above the ground, whereas monopoles must be mounted directly on the ground, the monopoles' radiation patterns are more greatly affected by resistance in the earth, and the radiation pattern with elevation inherently differs.
• The electrocaloric effect (ECE) is a phenomenon observed in dielectric materials, where a reversible temperature/entropy change occurs due to the alignment and reordering of dipoles under an applied electric field.
• The elementary magnetic constituents of spin ice are magnetic dipoles, so the emergence of monopoles is an example of the phenomenon of fractionalization.
• Working with Aharon Casher, they predicted the Aharonov–Casher effect, the electrodynamic dual of the Aharonov–Bohm effect with magnetic dipoles and charges.
• Retarding field analyzers can be installed in drift regions, dipoles, quadrupoles, and wiggler magnets.
• 5 MHz in -second pulses, applied to the antenna, a "bedspring" reflective array antenna composed of an 8x8 array of half wave dipoles and reflectors that provided 24 dB of gain.
• The DDA was also extended to employ rectangular or cuboid dipoles, which are more efficient for highly oblate or prolate particles.
