METHOD OF ATTENUATING ENERGY OF ELECTROMAGNETIC RADIATION Russian patent published in 2013 - IPC H01Q17/00 G21F7/00

Abstract RU 2490762 C2

FIELD: radio engineering, communication.

SUBSTANCE: method of attenuating energy of electromagnetic radiation is based on absorption of said energy in water vapour. Water vapour is ionised with electromagnetic waves with frequency higher than 7.5-10¹³ Hz (lower bound of the UV region) with water vapour concentration of at least $1 0^{- 3} \frac{g}{c m^{3}}$ and specific ionising power of at least $1 \frac{m W}{с m^{3}} .$

EFFECT: invention enables to absorb units of radiation in the millimetre and centimetre wavelength range.
