The shielding materials allow to solve two basic tasks: protect conductor from the externally-produced noise or to not allow the propagation of electromagnetic waves in the space beyond the limits of the screen itself.
As reports associate, for Japanese scientists it was possible to develop a paint with the particles of oxides iron and aluminum, which reflects the signals of wi-Fi networks or other sources, which work at the frequency up to 100 GHz. According to the inventors, they can create a paint, which reflects radio waves for more than 200 GHz. The cost of one kilogram of paint will not exceed $16.
Besides the sphere of information protection , this paint can be used in theaters and other public places, where the work of cell phones and communication line devices must be blocked. In the medical establishments, this paint will protect the sensitive equipment, which transmits information along wireless channels, from the externally-produced noise. Covering with this paint clothing, it is possible to protect from electromagnetic radiation children and pregnant women, and also all desiring to safeguard itself from the action of contemporary civilization.
