Abstract
We derive the first dynamic correction to the effective refractive index for a square array of cylinders (of finite or infinite refractive index), subject to a low frequency incident radiation. This correction also imposes constraints on the wavenumber region for which the Lorentz-Lorenz formula in two dimensions is accurate.Keywords
