NAME

Photonic::NonRetarded::EpsTensor

VERSION

version 0.010

SYNOPSIS

   use Photonic::NonRetarded::EpsTensor;
   my $eps=Photonic::NonRetarded::EpsTensor->new(geometry=>$g);
   my $epsilonTensor=$eps->evaluate($epsA, $epsB);

DESCRIPTION

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

METHODS

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

  Initializes the structure.

  $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)

• evaluate($epsA, $epsB)

  Returns the macroscopic dielectric function for a given value of the dielectric functions of the host $epsA and the particle $epsB.
