VERSION

version 0.003

SYNOPSIS

use Photonic::NonRetarded::EpsL;
my $eps=Photonic::NonRetarded::EpsL(nr=>$nr);
my $epsilonLongitudinal=$eps->evaluate($epsA, $epsB);

DESCRIPTION

Calculates the longitudinal dielectric function for a given fixed Photonic::NonRetarded::AllH structure as a function of the dielectric functions of the components.

METHODS

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

  Initializes the structure.

  $nr is a Photonic::NonRetarded::AllH structure.

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

  $small is the criteria of convergence

• evaluate($epsA, $epsB)

  Returns the macroscopic dielectric function for a given value of the dielectric functions of the host $epsA and the particle $epsB.

ACCESORS (read only)

• epsL

  The longitudinal macroscopic function obtained in the last calculation.

• nh

  The maximum number of Haydock coefficients to use.

• nhActual

  The actual number of Haydock coefficients used in the last calculation

• converged

  Flags that the last calculation converged before using up all coefficients

• small

  Criteria of convergence. 0 means don't check.
