Purcell effect, surface modes and nonlocality in hyperbolic metamaterials

We have performed rigorous dispersion analysis and showed clearly impact of nonlocality on properties of multilayered metal-dielectric metamaterial. The main discovered effect is an appearance of additional extraordinary waves in the metamaterial which leads to the splitting of the TM-polarized beam at the air-metamaterial interface. Also, we have studied surface modes and Purcell effect in these metamaterials.
