Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun The aggregate of cytoplasmic or extranuclear genetic material in an organism.
  • noun A quantum of collective electron oscillation in a metal, considered as a quasiparticle and analogous to the oscillations of a plasma consisting of stationary positive ions and a gas of electrons.

  • noun A flourlike food preparation made from skim milk, and consisting essentially of the unaltered proteid of milk. It is also used in making biscuits and crackers, for mixing with cocoa, etc. A mixture of this with butter, water, and salt is called Plasmon butter, and resembles clotted cream in appearance.

Examples

  • Ordinarily, visible-light lasers cannot be narrower than the wavelength of the light being used, but researchers have found ways around that fundamental limit by using a virtual particle called a plasmon, which is like a wave passing through a cloud of electrons.

  • The semiconductor, called a plasmon, can focus light the size of a single protein in a space that is smaller than half its wavelength while maintaining laser-like qualities that allow it to not dissipate over time.

  • A plasmon is a collective excitation of the electronic "fluid" in a piece of conducting material, like ripples on the surface of a pond are a collective mode of the water molecules of the liquid.

  • The team, led by Professor David Cumming and Dr Tim Drysdale from the University's department of electronics and electrical engineering, will take advantage of a phenomenon called plasmon resonance in their efforts to create a microchip for cameras and other imaging equipment that will produce sharper, more colourful images.
