version 0.009

SYNOPSIS

   use Photonic::Retarded::EpsilonP;
   my $eps=Photonic::Retarded::EpsilonP->new(haydock=>$h, nh=>$nh);
   my $EpsTensor=$W->evaluate($epsB);

DESCRIPTION

Calculates the macroscopic dielectric tensor component for a given fixed Photonic::Retarded::AllH structure as a function of the dielectric functions of the components.

NOTE: Only works for polarizations along principal directions.

METHODS

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

  Initializes the structure.

  $h Photonic::Retarded::AllH describing the structure and some parametres.

  $nh is the maximum number of Haydock coefficients to use.

  $smallE is the criterium of convergence (default 1e-7) for Haydock coefficients and for the continued fraction. From Photonic::Roles::EpsParams.

  $k is a flag to keep states in Haydock calculations (default 0)

• evaluate($epsB)

  Returns the macroscopic dielectric component for a given value of the dielectric function of the particle $epsB. The host's response $epsA is taken from the AllH structure.

  NOTE: Only works along principal directions.

ACCESORS (read only)

• epsilon

  The macroscopic dielectric projection of the last operation

• All accesors of Photonic::Retarded::Wave
