    "abstract": "We demonstrate that under certain conditions, fractional Talbot revivals can\noccur in heterostructures of composite metamaterials, such as multilayer\npositive and negative index media, metallodielectric stacks, and\none-dimensional dielectric photonic crystals. Most importantly, without using\nthe paraxial approximation we obtain Talbot images for the feature sizes of\ntransverse patterns smaller than the illumination wavelength. A general\nexpression for the Talbot distance in such structures is derived, and the\nconditions favorable for observing Talbot effects in layered heterostructures\nis discussed.",
