Cascading Optical Negative Index Metamaterials

Cascading Optical Negative Index MetamaterialsAbstract
We use a spatial harmonic analysis (SHA) method to homogenize optical metamaterials with a negative refractive index; the method provides a more general approach than other methods for estimating the effective index of materials arranged of cascaded elementary layers. The approach is validated for a single layer and a triple layer two dimensional metal grating.
