What is an EMC shielding shelter
An EMC shielding shelter, also called a Faraday cage or anechoic chamber, is a structure designed to protect electronic devices from electromagnetic interference (EMI) from outside and to prevent the spread of electromagnetic emissions generated by the device to the outside world. It consists of thick metal walls, which can be made of various materials, such as stainless steel, copper, aluminium or iron. The walls are usually made of a mesh or grid structure to prevent electromagnetic waves from entering the chamber and to ensure that electromagnetic emissions inside the chamber are attenuated and dissipated. The chamber is also equipped with shielded doors, shielded windows, electrical seals and earth conductors to ensure that the structure is completely electrically shielded. In addition, the chamber is usually equipped with insulating materials to prevent the reflection of electromagnetic waves inside the chamber, thus creating an anechoic environment. EMC shielding is important in many applications, such as in the design of medical, avionics, military, automotive and telecommunications devices. These devices must operate in electromagnetically complex environments and may be subject to electromagnetic interference from other equipment. In addition, they may generate electromagnetic emissions that could disturb other devices in the vicinity.
What it is for
An EMC shielding shelter is an important structure designed to protect electronic devices from external electromagnetic interference and to prevent the spread of electromagnetic emissions generated by the device to the outside world. The main purpose of an EMC shielding shelter is to prevent electromagnetic interference or radio frequency interference from affecting sensitive electronics. This is achieved by using a metal shield to absorb electromagnetic interference transmitted through the air. The metal screen completely surrounds the sensitive electronics or transmission electronics. The shield absorbs the transmitted signals and causes a current within the shield body. This current is absorbed by a ground connection or a virtual ground plane.
