Photonic::Retarded::GreenP

VERSION

version 0.010

SYNOPSIS

use Photonic::Retarded::GreenP;
my $green=Photonic::Retarded::GreepP(haydock=>$h, nh=>$nh);
my $greenProjection=$green->evaluate($epsB);

DESCRIPTION

Calculates the dielectric function for a given fixed Photonic::Retarded::AllH structure as a function of the dielectric functions of the components.

METHODS

• new(haydock=>$h, nh=>$nh, smallE=>$smallE)

  Initializes the structure.

  $h is a Photonic::Retarded::AllH structure (required).

  $nh is the maximum number of Haydock coefficients to use (required).

  $smallE is the criteria of convergence (defaults to 1e-7)

• evaluate($epsB)

  Returns the macroscopic projected green'S function for a given complex value of the dielectric functions of the particle $epsB.

ACCESORS (read only)

• haydock

  The Retarded::AllH structure

• epsA epsB

  The dielectric functions of component A and component B used in the last calculation.

• u

  The spectral variable used in the last calculation

• Gpp

  The projected Green's function of the last calculation.

• nh

  The maximum number of Haydock coefficients to use.

• nhActual

  The actual number of Haydock coefficients used in the last calculation

• converged

  Flags that the last calculation converged before using up all coefficients

• smallE

  Criteria of convergence. 0 means don't check. From Photonic::Roles::EpsParams.
