Detailed Description

template<int D>
class Pscf::Rpc::BinaryStructureFactorGrid< D >

BinaryStructureFactorGrid evaluates AB copolymer structure factors.

This class evaluates the structures factors for all wavevectors within a specified region of a Fourier space grid.

A structure factor for a wavevector k for AB diblock defined as an expectation value

\[ S(k) = n/(V \chi N)^2 <W_(k)W_(-k)> - 1/(2 \chi N) \]

where, V is system volume, and \(W_(k)\) is a Fourier mode of fluctuating field
