NAME
Photonic::Retarded::EpsilonP
VERSION
version 0.010
SYNOPSIS
use Photonic::Retarded::EpsilonP;
my $eps=Photonic::Retarded::EpsilonP->new(haydock=>$h, nh=>$nh);
my $EpsTensor=$W->evaluate($epsB);
DESCRIPTION
Calculates the macroscopic dielectric tensor component for a given fixed Photonic::Retarded::AllH structure as a function of the dielectric functions of the components.
NOTE: Only works for polarizations along principal directions.
METHODS
new(haydock=>$h, nh=>$nh, smallE=>$smallE)
Initializes the structure.
$h Photonic::Retarded::AllH describing the structure and some parametres.
$nh is the maximum number of Haydock coefficients to use.
$smallE is the criterium of convergence (default 1e-7) for Haydock coefficients and for the continued fraction. From Photonic::Roles::EpsParams.
$k is a flag to keep states in Haydock calculations (default 0)
evaluate($epsB)
Returns the macroscopic dielectric component for a given value of the dielectric function of the particle $epsB. The host's response $epsA is taken from the AllH structure.
NOTE: Only works along principal directions.
ACCESORS (read only)
epsilon
The macroscopic dielectric projection of the last operation
