SYNOPSIS

   use Photonic::NonRetarded::SH;
   my $nrsh=Photonic::NonRetarded::SH->
             new(shp=>$shp, epsA1=>$epsA1, epsB1=>$epsB1,
                 epsA2=>$epsA2, epsB2=>$epsB2); 
   my $PL_G=$nrsh->selfConsistentL_G;

DESCRIPTION

Calculates the non retarded SH polarizations and fields of arbitrary a periodic composite made up of centrosymmetric isotropic component materials, using the continuous dipolium model.

METHODS

• new(shp=>$shp, epsA1=>$epsA1, epsB1=>$epsB1, epsA2=>$epsA2, epsB2=>epsB2);

  Initializes the structure

  $shp is a Photonic::NonRetarded::SHP object with the invariant part of the data structures for the calculations

  $epsA1, $epsB1, $epsA2, $epsB2 are the dielectric functions of the A and B materials at the fundamental and the second harmonic frequency
