RF shielded test enclosures, also known as Faraday cages, are enclosed spaces designed to block electromagnetic fields in and out. They are constructed with metallic materials like steel, copper or aluminum sheeting to provide radio frequency (RF) shielding. The metallic walls act as a Faraday shield to protect internal equipment and experiments from exterior RF interference as well a... https://timessquarereporter.com/business/rf-shielded-test-enclosures--the-need-for-electromagnetic-radiation-protection
