use Photonic::WE::R2::Metric; my $gGG=Photonic::WE::R2::Metric->new( geometry=>$geometry, epsilon=>$eps, wavenumber => $q, $wavevector=>k); f($gGG->value);
Calculates the retarded metric tensor g_{GG'}^{ij} for use in the calculation of the retarded Haydock coefficients for the wave equation.
new(geometry=>$g, epsilon=>$e, $wavenumber=>$q, $wavevector=>$k);
Create a new Ph::WE::R2::Metric object with Geometry $g, dielectric function of the reference $e, vacuum wavenumber $q=omega/c and wavevector $k. $q and $k are real.
geometry
The Photonic::Types::Geometry object that describes the geometry of the system.
epsilon
A reference real dielectric function.
wavenumber
The vacuum wavenumber, w/c, 2PI/lambda.
wavevector
The wavevector.
value
The actual metric tensor as a complex PDL. Provided by implementation.
