CONTRIBUTIONS TO ACHIEVE A COMPOSITE MATERIAL FOR ADVANCED ELECTROMAGNETIC SHIELDING OF LIVING AND WORKSPACES

The paper refers to a new material for electromagnetic shielding of living and workspaces in order to reduce the electro smog. The material and manufacturing technology described comes in support  of  the  activities  carried  on  by  electromagnetic compatibility  of  high  frequency  radiation emitted by mobile antennas, radar, cell phones, microwaves, computers, wireless networking, on the environment. The shielding material described by the authors is of composite type and it is in the form of nets with fine meshes made of thin steel wires on which a high-purity copper shirt, coated in its turn by a polymer shirt, is deposited, the latter one’s aim is to protect against oxidation of copper coating. Nets, supplied in rolls, can be integrated under the plaster of working and living spaces performing an advanced electromagnetic shielding throughout the duration of building those spaces belong to.
