DESCRIPTION

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

METHODS

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

  Initializes the structure.

  $nr is a Photonic::...::AllH structure (required).

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

  $smallE is the criteria of convergence for the continued fraction (defaults to 1e-7)

• 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)

• nr

  The ...::AllH structure

• epsA epsB

  The dielectric functions of component A and component B used in the last calculation.

• u

  The spectral variable used in the last calculation

• 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

• smallE

  Criteria of convergence for continued fraction. 0 means don't check.
