NAME
Photonic::Retarded::EpsilonTensor
VERSION
version 0.007
SYNOPSIS
use Photonic::Retarded::EpsilonTensor;
my $epsT=Photonic::Retarded::EpsilonTensor->new(metric=>$m, nh=>$nh);
my $EpsTensor=$W->evaluate($epsB);
DESCRIPTION
Calculates the macroscopic dielectric tensor for a given fixed Photonic::Retarded::Metric structure as a function of the dielectric functions of the components.
METHODS
new(metric=>$m, nh=>$nh, small=>$small, 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.
$small is the criteria of convergence (default 1e-7)
$k is a flag to keep states in Haydock calculations (default 0)
evaluate($epsB)
Returns the macroscopic dielectric tensor for a given value of the dielectric function of the particle $epsB. The host's response $epsA is taken from the metric.
ACCESORS (read only)
epsilonTensor
The macroscopic dielectric tensor of the last operation
