<p>The invention relates to a process for the electromagnetic shielding of dwelling places against the effect of high frequency electromagnetic radiation in the environment. The process consists in using rows of LC type oscillators soldered on some polyethylene strips inserted in plates-shaped type building material, during the fabrication process thereof, each oscillator on these strips being tuned on a specific frequency which the oscillator takes off from the environment, the energy of electromagnetic radiation being dissipated as heat due to the coil resistivity and the dielectric losses of the capacitor. The oscillators on the polyethylene strips (5) comprise some Archimede spiral-shaped plane coils (3 and 4) and some capacitor armatures (1 and 2) in the shape of a disk, manufactured from aluminum foil by photochemical erosion or mechanical stamping, the dielectric of the capacitor being given by the very polyethylene strip (5), the oscillation frequency (f) to resonance being given by the number of coil turns (3 and 4) and the value of area (A) of the capacitor armatures (1 and 2).</p> |
