SYNOPSIS

   use Photonic::LE::NR2::Field;
   my $nrf=Photonic::LE::NR2::Field->new(...);
   my $field=$nrf->evaluate($epsA, $epsB);

DESCRIPTION

Calculates the non retarded electric field for a given fixed Photonic::Geometry structure and given dielectric functions of the components.

METHODS

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

  Initializes the structure.

  $nr Photonic::LE::NR2::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($epsA, $epsB...)

  Returns the microscopic electric field for given dielectric functions of the host $epsA and the particle $epsB.
