An electromagnetically shielded or reflecting device having a film of shielding or reflecting material and a device for obtaining, in a dielectric material volume, selective propagation of electromagnetic radiation in predetermined frequency band. The shielding or reflecting material includes a polymer, and electrically conducting particles substantially randomly dispersed in the polymer The film is used in shielding objects against electromagnetic radiation across a range of frequencies, The device for obtaining, in a dielectric material volume, selective propagation of electromagnetic radiation in predetermined frequency band includes a dielectric material volume extending from a first surface to a second surface, a first number of cavities, a second number of cavities, each cavity from the first and second numbers extending from the first surface to the second surface, the cavities being substantially randomly distributes on the first or second surface and being filed with an electrically conducting material.
