Faddeeva function : ウィキペディア英語版 | Faddeeva function The Faddeeva function or Kramp function is a scaled complex complementary error function, : It is related to the Fresnel integral, to Dawson's integral, and to the Voigt function. The function also arises frequently in problems involving small-amplitude waves propagating through Maxwellian plasmas, and in particular appears in the plasma's permittivity from which dispersion relations are derived, hence it is sometimes referred to as the plasma dispersion function〔http://nlpc.stanford.edu/nleht/Science/reference/errorfun.pdf〕〔 (although this name is sometimes used instead for the rescaled function defined by Fried and Conte〔〔(Richard Fitzpatrick ), (Plasma Dispersion Function ), ''(Plasma Physics )'' lecture notes, University of Texas at Austin (2011/3/31).〕). The function is also used in the analysis of electromagentic waves of the type used in AM radio. Groundwaves are verticaly polarised waves propagating over a lossy ground with finite resistivity and permittivity. == Properties ==
