Abstract
An electromagnetically active composite has an electrically-nonconductive host matrix and electrically-conductive nanostrand bodies embedded in a substantially uniform distribution throughout the host matrix. Each of the nanostrand bodies comprises a volume containing at least one nanostrand of filamentary metal. Adjacent nanostrand bodies that are sufficiently mutually proximate will interact electromagnetically with each other. The filamentary metal of the one or more nanostrands in each of the nanostrand bodies occupies a deminimus fraction of the overall volume occupied by the at least one nanostrand that comprises each of the nanostrand bodies. The filamentary metal is chosen from among the group of metals that includes nickel, nickel aluminides, iron, iron aluminides, alloys of nickel and iron, and alloys of nickel and copper. Individual nanostrands of the nanostrand bodies have an average diameter in a range of from about 10 nanometers to about 4000 nanometers, and the average diameter of the nanostrand bodies is in a range of from about one micron to about 3000 microns.
