  2. Electromagnetic shielding - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_shielding

    Electromagnetic shielding that blocks radio frequency (RF) electromagnetic radiation is also known as RF shielding. EMF shielding serves to minimize electromagnetic interference. The shielding can reduce the coupling of radio waves, electromagnetic fields, and electrostatic fields.

  3. Faraday cage - Wikipedia

    en.wikipedia.org/wiki/Faraday_cage

    The reception or transmission of radio waves, a form of electromagnetic radiation, to or from an antenna within a Faraday cage is heavily attenuated or blocked by the cage; however, a Faraday cage has varied attenuation depending on wave form, frequency, or the distance from receiver or transmitter, and receiver or transmitter power.
