SYNOPSIS

use Photonic::WE::R2::GreenP;
my $green=Photonic::WE::R2::GreepP->new(haydock=>$h, nh=>$nh, epsB=>$epsB);
my $greenProjection=$green->Gpp;
my $WaveProjection=$green->waveOperator;
my $EpsP=$green->epsilon;

DESCRIPTION

Calculates the macroscopic Green's function projected along some direction. Based on the wave equation for a binary metamaterial, with a non-dissipative host.

ATTRIBUTES

• haydock

  Photonic::WE::R2::Haydock structure (required).

• nh

  Maximum number of Haydock coefficients to use (required).

• epsB

  The dielectric functions of component B (required)

• smallE

  criteria of convergence (defaults to 1e-7)

• epsA

  The dielectric functions of component A, got from the Haydock's epsilon

• u

  The spectral variable from the calculation

• Gpp

  Returns the macroscopic projected Green's function for a given complex value of the dielectric functions of the particle epsB.

• nhActual

  The actual number of Haydock coefficients used in the calculation

• converged

  Flags that the calculation converged before using up all coefficients

• waveOperator

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

  NOTE: Only works along principal directions, as it treats Green's function as scalar.

• epsilon

  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 Haydock structure.

  NOTE: Only works for polarizations along principal directions.
