Query: Effective Constitutive Parameters of Plasmonic Metamaterials: A Direct
  Approach   We introduce a general implementation of the recently proposed homogenization
theory [Tsukerman, J. Opt. Soc. Am. B 28, 577 (2011)] allowing one to retrieve
all 36 linear constitutive parameters of any 3D metamaterial with
parallelepipedal unit cells. The effective parameters are defined directly as
linear relations between pairs of coarse-grained fields, in contrast with
methods where these parameters are obtained from reflection/transmission data
or other indirect considerations. The method is applied to plasmonic
metamaterials with spherical gold particles and split-ring resonators (SRR),
respectively. In both cases, the expected physical behavior is reproduced
almost perfectly, with no unphysical artifacts.
