What Is an RF-Shielded Room?
Equipment that uses electricity generates electromagnetic waves. Therefore, equipment and devices are constantly affected by various electric fields. They can also affect their surroundings.
RF-shielded room is designed to block the influence of electromagnetic waves and magnetic fields from the outside and prevent them from being emitted outside.
Structurally, the room is covered with conductive materials such as metal or wire mesh. It may be constructed in a new building or, in the case of an existing building, assembled with panels that can be assembled inside. Therefore, each room is designed according to the purpose of use, the content of measurement, and the location and environment in which it is to be installed.
Uses of RF-Shielded Rooms
Shielded rooms create an environment for product development and quality control of precision instruments, electronic devices, and other products. They are also used to prevent electromagnetic noise (unwanted radio waves) generated by equipment and devices inside the facility from affecting equipment and devices outside the facility. In some facilities where wireless microphones and other equipment are used, it is necessary to create an environment that prevents interference caused by external radio waves and effectively uses radio waves.
- Measurement rooms with equipment for measuring biomagnetic fields such as MRI, magnetoencephalography, and magnetocardiography.
- Computer rooms for confidentiality
- Measurement rooms for electromagnetic interference
- Computer rooms
- Recording studios
Principles of RF-Shielded Rooms
RF-shielded rooms can be broadly classified according to their purpose and the frequency range they are designed to handle.
- For electrostatic shielding RF-shielded rooms are used to maintain a constant room potential. For example, an EEG room or a hearing test room.
- For magnetic shielding RF-shielded rooms for geomagnetic fields up to 10 kHz.
- For planar electromagnetic shielding RF-shielded rooms for 10kHz to 40GHz. Noise testing rooms for electronic equipment, anechoic chambers, recording studios, etc.
The shield is often referred to as electromagnetic shielding in EMC countermeasures. Electromagnetic shielding is often used for EMC and imminence countermeasures for electronic equipment.
The principle of electromagnetic shielding is based on the property of conductive materials such as wire mesh and metal plates to reflect electromagnetic waves. A room covered with these conductive materials is an RF-shielded room.
In producing RF-shielded rooms, it is essential not only to shield the electromagnetic waves generated in the space or influenced by the outside but also to shield the electromagnetic noise leaking from both sides. In particular, the shielding treatment of openings (doors, windows, air conditioning openings, etc.) is crucial.
