RADIO ABSORBENT MATERIAL Russian patent published in 2009 - IPC H01Q17/00 

FIELD: physics; radio.

SUBSTANCE: present invention relates to radio engineering, particularly to material for shielding electromagnetic radiation when making radio-electronic equipment. Improvement of radio absorbent properties of the material is achieved due to introduction into polymer dielectric material, containing micro-granules of a matrix which are transparent for radiation in the radio-wave spectrum, of micro-granules of substances which can absorb electrical and magnetic components of radio-wave radiation. Each type of micro-granules contains only one radio absorbent substance, chosen from a group comprising ferrite, copper, and fullerene C₇₀, uniformly distributed in the whole volume of the material of the matrix in form of nanoclusters.

EFFECT: improved radio absorbent properties of material, on the electrical and magnetic components of electromagnetic radiation in the radio-waves spectrum.
