SYNOPSIS
use Photonic::WE::R2::Field;
my $nrf=Photonic::WE::R2::Field->new(...);
my $field=$nrf->evaluate($epsB);
DESCRIPTION
Calculates the retarded electric field for a given fixed Photonic::Geometry structure and given dielectric functions of the components.
METHODS
new(haydock=>$haydock, nh=>$nh, smallE=>$smallE)
Initializes the structure.
$haydock Photonic::WE::R2::Haydock is a Haydock calculator for the structure, *initialized* with the flag keepStates=>1 (Photonic::Types::HaydockSave, as defined in Photonic::Types).
$nh is the maximum number of Haydock coefficients to use.
$smallE is the criteria of convergence (default 1e-7) for Field calculations
evaluate($epsB)
Returns the microscopic electric field for given dielectric functions of the host (which it gets from the Haydock calculator's epsilon) and the particle $epsB.
