SYNOPSIS

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

DESCRIPTION

Calculates the retarded green's tensor for a given fixed Photonic::WE::S::Metric structure as a function of the dielectric functions of the components.

ATTRIBUTES

  • keepStates

    Value of flag to keep Haydock states in Haydock calculations (default 0)

  • metric

    Photonic::WE::S::Metric describing the structure and some parameters.

  • nh

    The maximum number of Haydock coefficients to use.

  • smallH, smallE

    Criteria of convergence of Haydock coefficients and continued fraction. 0 means don't check. (default 1e-7)

  • haydock

    Array of Photonic::WE::S::Haydock structures, one for each polarization

  • reorthogonalize

    Reorthogonalize haydock flag

  • greenP

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

  • greenTensor

    The Green's tensor calculated

  • nhActual

    The actual number of Haydock coefficients used in the last calculation

  • converged

    Flags that the last calculation converged before using up all coefficients

  • waveOperator

    The macroscopic wave operator of the last operation

  • epsilonTensor

    The macroscopic dielectric tensor
