Summary:
In this paper, the forward scattering sum rule is used to investigate scattering and absorption of electromagnetic energy in periodic metamaterials. The sum rule is valid for arbitrary structures composed of linear and passive materials and it shows that the all spectrum interaction between the structure and the electromagnetic field is proportional to the polarizability of the structure. The theoretical results are illustrated with numerical examples for nano-spheres.
