DESCRIPTION

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

The consuming class needs to supply these methods to inform lazy-building of epsL:

• _build_epsL

ATTRIBUTES

• haydock

  The ...::Haydock structure

• epsL

  The longitudinal macroscopic function calculated from the parameters (lazy-built).

• nh

  The maximum number of Haydock coefficients to use (required).

• nhActual

  The actual number of Haydock coefficients used in the 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. (defaults to 1e-7)
