GTPhDielectric

GTPhDielectric[reciprocal lattice vector,structure,permittivity structure,permittivity background,geometry]
gives the Fourier transform of .

DetailsDetails

  • The permittivity does not enter the master equation directly, but the Fourier transform of . If the structure is geometrically simple, the Fourier transform can be evaluated analytically. Such Fourier transforms are implemented via GTPhDielectric. The Fourier transform is evaluated at a certain reciprocal lattice vector for a structure.
  • If structure = "Help" is used, all implemented structures together with the meaning of the list geometry are listed.
  • The dielectric contrast is given by permittivity structure and permittivity background.

  • This module will finally be substituted by GTPhDCObjects.
