GTPhPermittivity

GTPhPermittivity[reciprocal basis,cutoff,objects,background]
gives for all reciprocal lattice vectors used in the master equation with .

DetailsDetails

  • Two methods of the construction of the master equation, i.e. the eigenvalue problem to construct photonic band structures are possible. First, the are calculated on the fly during the construction of the eigenvalue problem, second all which are necessary are calculated beforehand. GTPhPermittivity calculates all the necessary beforehand.
  • The following options can be given:
  • GOPixelTrueDecides the type of calculation: pixelmap or list of objects
    GOVerboseFalseControls the output of additional information
  • See: W. Hergert, M. Geilhufe, Group Theory in Solid State Physics and Photonics. Problem Solving with Mathematica, chapter 10.4
