Meta Materials and Meta Surfaces

Meta Materials  and Meta Surfaces are rising research fields nowadays owing to their anomalous and largely tunable properties of light scattering in ultra compact volume. Performances of meta materials and meta surfaces  are dependent on their subwavelength separation and geometric parameters of each meta-atom, a fundamental constituent of meta materials and meta surfaces. Meta atoms are composed of one or more subwavelength nanostructures with noble metals or high index dielectrics. They are engineered to exhibit desired effective local optical responses, which can be expressed in terms of amplitude and phase or electric and magnetic polarizabilities
