Thank you for mentioning your recent paper on the subject, I was not
aware of it. The conclusions are rather bad for the use of DDA in the
field of nano-plasmonics, at least until the reason for the poor
convergence of Qabs is known (and perhaps overcome). It would seem
that T-matrix methods (and EBCM, NFM with DS, ...) are more suited to
this class of particles. The cause for the low accuracy of DDA in this
regime is a very intriguing question though. Could some insight be
gained from comparing the instantaneous internal polarisation with the
internal field calculated using, e.g., Mie theory for a sphere? Such a
comparison might illustrate the phase error that appears to undermine
the estimation of the absorption loss.
Best regards,
baptiste
