Porous material for protection from electromagnetic radiation

Abstract

Abstract. It is shown that the porous glass crystalline material obtained by a low temperature technology can be used not only for thermal insulation, but also for lining of rooms as protective screens decreasing harmful effect of electromagnetic radiation as well as to establish acoustic chambers and rooms with a low level of electromagnetic background. The material interacts with electromagnetic radiation by the most effective way in a high frequency field (above 100 GHz). At the frequency of 260 GHz the value of the transmission coefficient decreases approximately in a factor times in comparison with foam glass.

Microarc synthesis of nanostructured radiation-absorbing coatings on aluminum and titanium surfaces

“…The ability of the process to form high-temperature oxide modifications is confirmed either by a number of published sources [1][2][3][4][5][6][7][8] or in the present study.…”

“…The reason was, first and foremost, in different compositions of the electrolytes. A miscalculation happened during the development of electrolytes for oxidation, namely, the presence of Co 2+ and Fe(CN) 6 3-in the solution that gave an insoluble deposition was not taken into account:…”
