METHODS AND COMPOSITIONS FOR ENERGY DISSIPATION

摘要

A method for forming a composition exhibiting energy dissipation in at least a portion of the frequency range from about 1 GHz to about 20 GHz can comprise treating a magnetic lossy material to increase the brittleness of the material, processing at least a portion of the magnetic lossy material into a powder, and mixing at least a portion of the powder with a dielectric resin, wherein the percentage volume of the powder relative to the total volume of the composition is configured such that dissipation of incident electromagnetic radiation is substantially optimized in at least a portion of the frequency range from about 1 GHz to about 20 GHz.
