FIELD: medical engineering. SUBSTANCE: device operates by transforming electromagnetic field of natural and artificial origin into electromagnetic field structured in frequency, spatially and informationally. Device has a set of regular tetrahedral pyramids enclosed one inside another, having the same symmetry axis and bases belonging to the same plane. All pyramids have common apex, the angles of base of every following pyramid are located in the middle of the preceding pyramid side. The whole complex is divided into tiers by planes running in parallel to base. Rib of each of the pyramids is connectable to the center of the nearest facet of the next pyramid internal with respect to the former one with a vertical partition. The device is manufacturable from glass for utilizing the whole visible spectrum range of electromagnetic radiation. EFFECT: selective special purpose treatment for improving composition and structure of various materials an applying positive influence upon life and metabolism processes. 7 cl, 5 dwg
