use Photonic::LE::NP::EpsTensor; my $eps=Photonic::LE::NP::EpsTensor->new( epsilon=>$e, geometry=>$g); my $epsilonTensor=$epsTensor;
Calculates the macroscopic dielectric tensor for a given fixed Photonic::Geometry structure as a function of the dielectric functions of the components.
new(epsilon=>$e, geometry=>$g, nh=>$nh, smallH=>$smallH, smallE=>$smallE, keepStates=>$k)
Initializes the structure.
$e PDL::Complex is the dielectric function as a complex scalar field
$g Photonic::Geometry describing the structure
$nh is the maximum number of Haydock coefficients to use.
$smallH and $smallE are the criteria of convergence (default 1e-7) for the Haydock coefficients and the tensor calculations.
$k is a flag to keep states in Haydock calculations (default 0)
A PDL::Complex PDL giving the value of the dielectric function epsilon for each pixel of the system
Value of flag to keep Haydock states
Array of Photonic::LE::NP::AllH structures, one for each direction
Array of Photonic::LE::NP::EpsL structures, one for each direction.
The valuated dielectric tensor
The maximum number of Haydock coefficients to use.
Flags that the last calculation converged before using up all coefficients
Criteria of convergence for Haydock and epsilon calculations. 0 means don't check.
