SYNOPSIS

use Photonic::WEM::S::Metric;
my $gGG=Photonic::WEM::S::Metric->new(
        mu => $mu,
        geometry=>$geometry, epsilon=>$eps,
        wavenumber => $q, $wavevector=>k);
f($gGG->value);

DESCRIPTION

Calculates the retarded metric tensor g_{GG'}^{ij} for use in the calculation of the retarded Haydock coefficients for the wave equation in a medium of arbitrary composition where the reference has no dissipation.

Implements 'Photonic::Roles::Metric'. Look there for the basic attributes and methods.

OTHER ATTRIBUTES

  • mu

    Real space complex magnetic permeability for each volume element.

METHODS

  • new(mu=>$mu, geometry=>$g, epsilon=>$e, $wavenumber=>$q, $wavevector=>$k);

    Create a new Ph::WEM::S::Metric object with permeability $mu, Geometry $g, dielectric function of the host $e, vacuum wavenumber $q=omega/c and wavevector $k. $q and $k are real.

  • apply($psi)

    Create and apply the magnetic metric to the state $psi provided in Haydock when it calls this method.
