SYNOPSIS

use Photonic::WE::R2::GreenP;
my $green=Photonic::WE::R2::GreepP(haydock=>$h, nh=>$nh);
my $greenProjection=$green->evaluate($epsB);

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.

METHODS

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

    Initializes the structure.

    $h is a Photonic::WE::R2::Haydock 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.

ACCESSORS (read only)

  • haydock

    The WE::R2::Haydock 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.
