SYNOPSIS

use Photonic::WE::R2::Green;
my $G=Photonic::WE::R2::Green->new(metric=>$m, nh=>$nh, epsB=>$epsB);
my $GreenTensor=$G->greenTensor;
my $WaveTensor=$G->waveOperator;
my $EpsTensor=$W->epsilonTensor;

DESCRIPTION

Calculates the retarded green's tensor for a given fixed Photonic::WE::R2::Metric structure as a function of the dielectric functions of the components. Includes the antysimmetric part, unless it is not desired.

Can also calculate the macroscopic wave operator.

ATTRIBUTES

• metric

  Photonic::WE::R2::Metric describing the structure and some parameters. (required)

• epsB

  Dielectric function of component B (particle) (required)

• nh

  The maximum number of Haydock coefficients to use.

• smallH, smallE

  Criteria of convergence (default 1e-7) for Haydock coefficients and continued fraction

• keepStates

  Value of flag to keep Haydock states (default 0)

• symmetric

  Flags that you only want the symmetric part of the Green's tensor, default 0.

• greenTensor

  Macroscopic Green's operator for the dielectric functions of the particle epsB. The host's response epsA is taken from the metric.

• epsA

  Dielectric function of component A (host) taken from the metric.

• u

  Spectral variable

• haydock

  Array of Photonic::WE::R2::Haydock structures, one for each polarization, from the geometry.

• reorthogonalize

  Reorthogonalize haydock flag

• greenP

  Array of Photonic::WE::R2::GreenP structures, one for each direction

• 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 the Green tensor.

• epsilonTensor

  Returns the macroscopic dielectric tensor from the wave operator.
