WebPermeability, permittivity, and refractive index are bulk, effective medium properties. Although our metamaterial consists of dis-crete scattering elements, it may be approxi-mated as an effective medium for wave-lengths that are larger than the unit cell size. The LHM used in these experiments had a unit cell dimension of 5 mm, a factor of 6 WebThe effect simulates absorption to the observer's eye in areas where a higher refractive index produces high contrast features. This impression is considered the optimum, particularly with cells and tissue in aqueous media because cell nuclei and organelles, for example, appear darker than the cytoplasm.
