    We theoretically and numerically demonstrate enhanced extended superradiance using a diamond epsilon near-zero metamaterial design. Due to the large spatial coherence in this metamaterial, we experience an ultra-high superradiant decay rate enhancement over distances greater than 13 times the free-space wavelength for both two emitters and many-body configurations of emitters. We observe a power enhancement three orders of magnitude higher than an incoherent array of emitters in bulk diamond, corresponding to an N2 scaling with the number of emitters characteristic of superradiance.
