SYNOPSIS

   use Photonic::LE::NP::EpsTensor;
   my $eps=Photonic::LE::NP::EpsTensor->new(
                     epsilon=>$e, geometry=>$g);
   my $epsilonTensor=$epsTensor;

DESCRIPTION

Calculates the macroscopic dielectric tensor for a given fixed Photonic::Geometry structure as a function of the dielectric functions of the components.

METHODS

• new(epsilon=>$e, geometry=>$g, nh=>$nh, smallH=>$smallH, smallE=>$smallE, keepStates=>$k)

  Initializes the structure.

  $e PDL::Complex is the dielectric function as a complex scalar field

  $g Photonic::Geometry describing the structure

  $nh is the maximum number of Haydock coefficients to use.

  $smallH and $smallE are the criteria of convergence (default 1e-7) for the Haydock coefficients and the tensor calculations.

  $k is a flag to keep states in Haydock calculations (default 0)

ACCESORS (read only)

• epsilon

  A PDL::Complex PDL giving the value of the dielectric function epsilon for each pixel of the system

• keepStates

  Value of flag to keep Haydock states

• nr

  Array of Photonic::LE::NP::AllH structures, one for each direction

• epsL

  Array of Photonic::LE::NP::EpsL structures, one for each direction.

• epsTensor

  The valuated dielectric tensor

• nh

  The maximum number of Haydock coefficients to use.

• converged

  Flags that the last calculation converged before using up all coefficients

• smallH smallE

  Criteria of convergence for Haydock and epsilon calculations. 0 means don't check.
