    "abstract": "It is commonly assumed that the long-wavelength limit of a metamaterial can\nalways be described in terms of effective permeability and permittivity\ntensors. This assumption holds true in all metamaterials considered up to now.\nHere we report that this assumption is false--there exist an entirely new class\nof metamaterials consisting of multiple interlocking disconnected metal\nnetworks, for which the effective long-wavelength theory is local, but the\neffective field is non-Maxwellian, and possesses much more internal degrees of\nfreedom than effective Maxwellian fields in a homogeneous medium.",
