Photonic::Retarded::GreenF

VERSION

version 0.010

SYNOPSIS

   use Photonic::Retarded::GreenF;
   my $G=Photonic::Retarded::GreenF->new(metric=>$m, nh=>$nh);
   my $GreenTensor=$G->evaluate($epsB);

DESCRIPTION

Calculates the asymetric part of the retarded green's tensor for a given fixed Photonic::Retarded::Metric structure as a function of the dielectric functions of the components.

METHODS

• new(metric=>$m, nh=>$nh, smallH=>$smallH, smallE=>$smallE, keepStates=>$k)

  Initializes the structure.

  $m Photonic::Retarded::Metric describing the structure and some parametres.

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

  $smallH and $smallE are the criteria of convergence (default 1e-7) for Haydock coefficients and continued fraction

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

• evaluate($epsB)

  Returns the macroscopic Green's operator for a given value of the dielectric functions of the particle $epsB. The host's response $epsA is taken from the metric.
