An electromagnetic radiation suppression covering conformable to a corresponding selected structure through reducing the extent of a surface dimension therein and containing one or more absorptive kinds of particles in a sheet of a corresponding thickness including such particles as iron oxides with adsorbed surface layers, such covering being formed through extruding a mixture of selected particles and binding material.

An electromagnetic radiation suppression covering for screening selected structures to thereby suppress to a selected extent, with respect to selected regions, presence of electromagnetic radiation of selected frequencies which has impinged on such screened structures, with screening of a corresponding selected structure to be accomplished through having a corresponding said suppression covering selectively conformed thereto, said suppression covering comprising a material means having at least a sheet portion of selected configuration formed of a polymeric binding material which is conformable to a corresponding selected structure through an initiation of a reduction in extent of a surface of said sheet portion in at least one direction due to forces internal thereto after said suppression covering has been position about such a corresponding selected structure, said sheet portion having distributed therein at least a first kind of particulate to thereby have permittivity and permeability parameters at least one of which has an imaginary part thereof with a magnitude that is at least one-tenth that of its corresponding real part for frequencies equal to at least some of said selected frequencies, said suppression covering having said first kind of particulate distributed in said sheet portion to thereby have an electromagnetic radiation reflection coefficient having a value at frequencies equal to said selected frequencies, for electromagnetic radiation containing at least some of said selected frequencies which is directly incident on said sheet portion at locations where it is conformed to a corresponding selected structure, of less than seven-tenths of that value of said reflection coefficient occurring at that location on at such a corresponding selected structure absent said suppression covering. A covered conductor about which, with respect to selected regions, presence of electromagnetic radiation of selected frequencies which has impinged on said covered conductor is suppressed to a selected extent, said covered conductor comprising: a conductor of a selected electrical conductivity which is elongated; and a covering material formed about said elongated conductor absent any seam extending substantially parallel to said axis thereof, and formed directly against said elongated conductor substantially absent of any other material being interposed therebetween, said covering material having distributed therein at least a first kind of particulate to thereby have permittivity and permeability parameters at least one of which has an imaginary part thereof with a magnitude that is at least one-tenth that of its corresponding real part of frequencies equal to at least some of said selected frequencies to result in said covering material having an electromagnetic radiation reflection coefficient with a value at frequencies equal to said selected frequencies for electromagnetic radiation containing at least some of said selected frequencies which is directly incident thereon, of less than seven-tenths of that value of said reflection coefficient at such a location on said conductor absent said covering material. A method for providing a means capable of suppressing to a selected extent, with respect to selected regions about a selected structure, presence of electromagnetic radiation at selected frequencies which has impinged on an arrangement including that selected structure, said method comprising: selecting a first kind of particulate having permittivity and permeability parameters at least one of which has an imaginary part thereof with a magnitude that is at least one-tenth that of its corresponding real part for frequencies equal to at least some of said selected frequencies; selecting a resin which will yield a polymeric binding material of a selected permittivity at said selected frequencies which is capable of having said first kind of particulate distributed therein and which is capable of being selectively conformed with said first kind or particulate therein to a corresponding structure; and mixing together said first kind of particulate and said resin and extruding a seamless tube of this mixture to result in said tube having an electromagnetic radiation reflection coefficient with a value at frequencies equal to said selected frequencies, for electrode magnetic radiation containing at least some of said selected frequencies which is directly incident on said tube at locations where it is conformed to a corresponding selected structure, of less than seven tenths of that value of said reflection coefficient occurring at such a location on that corresponding selected structure absence said tube.
