RSOZ for polydisperse systems

For a polydisperse fluid, composed of $n_{f}$ components, in a polydisperse matrix, composed of $n_{m}$ components, written in matrix form in Fourier space (see Eq. 18 of Ref. 1):

${\tilde {H}}_{mm}={\tilde {C}}_{mm}+\rho _{m}{\tilde {C}}_{mm}{\tilde {H}}_{mm}$

${\tilde {H}}_{fm}={\tilde {C}}_{fm}+\rho _{m}{\tilde {C}}_{mm}{\tilde {H}}_{fm}+\rho _{f}{\tilde {C}}_{fm}{\tilde {H}}_{ff}-\rho _{f}{\tilde {C}}_{12}{\tilde {H}}_{fm}$

${\tilde {H}}_{ff}={\tilde {C}}_{ff}+\rho _{m}{\tilde {C}}_{fm}^{T}{\tilde {H}}_{fm}+\rho _{f}{\tilde {C}}_{ff}{\tilde {H}}_{ff}-\rho _{f}{\tilde {C}}_{12}{\tilde {H}}_{12}$

${\tilde {H}}_{12}={\tilde {C}}_{12}+\rho _{m}{\tilde {C}}_{fm}^{T}{\tilde {H}}_{fm}+\rho _{f}{\tilde {C}}_{ff}{\tilde {H}}_{12}+\rho _{f}{\tilde {C}}_{12}{\tilde {H}}_{ff}-2\rho _{f}{\tilde {C}}_{12}{\tilde {H}}_{12}$
