1. A receptacle having an interior space and an outer surface, the receptacle being formed of a thermoplastic matrix composite laminate comprised of a series of graphite layers and a series of metal mesh layers such that the series of graphite layers and the series of metal mesh layers within the laminate forming a series of interlaminar resonance chambers which tune the electromagnetic shielding characteristics to specific frequencies such that the resulting structure possesses Faraday cage properties for the interior space and such that for an incoming incident wave of a first frequency entering the laminate via the laminate's outer surface, at least a first portion of the electromagnetic radiation of the incident wave is absorbed by the metal mesh layers and a second portion of the incoming wave is internally reflected within the resonance chambers and exits the laminate via the outer surface as a reflected wave loss and wherein for an outgoing incident wave of a second frequency that is different relative to the first frequency entering the laminate via the inner surface, at least a third portion of the electromagnetic radiation of the outgoing wave passes directly through the laminate and exits the laminate through the laminate's outer surface and a fourth portion of the outgoing wave is internally reflected within the resonance chambers and exits the laminate via the outer surface as a 2nd transmission wave.
