NAME
Photonic::Retarded::Green
VERSION
version 0.009
SYNOPSIS
use Photonic::Retarded::Green;
my $G=Photonic::Retarded::Green->new(metric=>$m, nh=>$nh);
my $GreenTensor=$G->evaluate($epsB);
DESCRIPTION
Calculates the retarded green's tensor for a given fixed Photonic::Retarded::Metric structure as a function of the dielectric functions of the components.
METHODS
new(metric=>$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.
