Résumé

We show the important role played by the multipolar coupling between the illuminating field and magneto-electric scatterers even in the small particle limit ( λ/10). A general multipolar method is presented which, for the case of planar non centrosymmetric particles, generates a simple expression for the polarizability tensor that directly links the dipolar moment to the incident field. The relevancy of this approach is demonstrated by comparing thoroughly the dipolar moments predicted by the method with full numerical calculations.
