This can potentially be also used for calculation of surfaces charges for complex objects, which is a first step to simulate charged particles in the DDA - see Kundracik F.,...
Concerning the optimization and accuracy, there are a lot of ideas in Schmehl's thesis (1994) - https://www.researchgate.net/publication/260426740_The_Coupled-Dipole_Method_for_Light_Scattering_from_Particles_on_Plane_Surfaces . It includes building a table and doing 2D interpolation on it. The...
Another relevant ideas for improvement (bug fixes) were proposed by Sheila Edalatpour in May 2014. I have not been able to look into it yet, so I am putting it...
Similar ideas for 2D interpolation are described in the following paper for another method. But is completely applicable to the DDA. J. Waxenegger, A. Trügler, and U. Hohenester, “Plasmonics simulations...

This will also allow using rectangular dipoles with unequal dX and dY in the presence of substrate. See #245
The FFT acceleration should not require significant changes. Now we have direct interaction, which is a function of (z1-z2), and reflected part, which is a function of (z1+z2) due to...

Surface-plasmon polaritons (SPPs) may need separate consideration even in the case of homogeneous metallic substrate (with very low absorption). Although, they are not infinitely propagating scattering from or into SPPs...
