Comment on “Plasmonic nanoparticle monomers and dimers: from nanoantennas to chiral metamaterials” by Chigrin et al. in Appl Phys B (2011) 105:81–97
Chigrin et al. (Appl Phys B 105:81, 2011) have recently presented a general direct solution of the integral equation for the electric field inside the scatterer, which does not require inversion of integral operator or, equivalently, solution of large system of linear equations. This comment points out that the rigorous applicability of the considered derivation is limited to ellipsoids much smaller than the wavelength.
