Applicable in the regime where wavelength exceeds resonator size.

Provides a new theoretical tool for meta-surface analysis.

Abstract

A meta-surface made of a collection of nano-resonators characterized an electric dipole and a magnetic dipole was studied in the regime where the wavelength is large with respect to the size of the resonators. An effective description in terms of an impedance operator was derived.
