1. An electromagnetic interference shielded apparatus comprising:

  • an electrical circuit in need of electromagnetic interference shielding; and

    a body at least partially surrounding the electrical circuit, the body comprising a composite material that includes at least two electrically conductive nanoscale fiber films overlying and spaced apart from one another with at least one insulating gap positioned between the at least two nanoscale fiber films,wherein the nanoscale fiber films and the insulating gap are effective to provide a substantial multiple internal reflection effect in shielding the electrical circuit from electromagnetic interference.
