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


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


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

    Initializes the structure.

    $nr Photonic::WE::S::AllH is a Haydock calculator for the structure, *initialized* with the flag keepStates=>1 (Photonic::Types::WE::S::AllHSave, 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.
