VERSION
version 0.009
SYNOPSIS
use Photonic::NonRetarded::SHChiTensor;
my $chi=Photonic::NonRetarded::SHChiTensor->new(geometry=>$g,
$densityA=>$dA, $densityB=>$dB, nh=>$nh, nhf=>$nhf,
filter=>$f, filterflag=>$ff);
my $chiTensor=$chi->evaluate($epsA1, $epsB1, $epsA2, $epsB2);
DESCRIPTION
Calculates the second harmonic susceptibility tensor for a given fixed Photonic::Geometry structure as a function of the dielectric functions of the components.
METHODS
new(geometry=>$g, densityA=>$da, densityB=>$db, nh=>$nh, nhf=>$nhf[, filter=>$ff][, smallH=>$smallH][, smallE=>$smallE])
Initializes the structure.
$g Photonic::Geometry describing the structure
$da, $db number densities for material A and B (in which units?)
$nh is the maximum number of Haydock coefficients to use.
$nhf is the maximum number of Haydock coefficients for the field calculation.
$ff is a (maybe smooth) cutoff function in reciprocal space to smothen the geometry.
$smallH and $smallE are the criteria of convergence (default 1e-7) for haydock coefficients and continued fraction. From Photonic::Roles::EpsParams.
evaluate($epsA1, $epsB1, $epsA2, $epsB2, [$kind])
Returns the macroscopic second Harmonic susceptibility function for a given value of the dielectric functions of the host $epsA and the particle $epsB at the fundamental 1 and second harmonic 2 frequency. $kind is an optional letter for testing purposes with values 'd' for dipolar, 'q' for quadrupolar, 'e' for external and 'f' for full selfconsistent calculation (the default).
