Hello everyone, I’m the editor, do you know absorbing materials? Today, the editor will analyze it specifically for you, and I hope it will be helpful to you.

The commonly referred to as microwave absorbing materials are our absorbing materials. About its experiment and design: the development of microwave anechoic chambers on microwave absorbing materials and anechoic chambers can be traced back to 1953, which is exactly the same year. The research of microwave absorbing materials began to go out of the laboratory and into the commercial field. At the same time, the first microwave anechoic chamber was built and began to be used in the testing of microwave absorbing performance. During the Second World War, the application of absorbing materials in radar became more and more important. Germany and the United States carried out a lot of work from the design, production and testing of absorbing bodies to performance improvement. Design of shielded chambers The main task of the design is how to improve the shielding effectiveness, and the key is the correct selection of shielding materials and node structure.


 
The location of the shielded room. Theoretically speaking, it should be as far away as possible from the interference source to reduce the electric field intensity of the interference. However, in actual engineering, it is often restricted by various conditions, especially because the interference factors often change, and new things may appear at any time during work. Therefore, in the design, it is often necessary to consider the electric field strength of a strong interference source nearby. Shielding rooms are often located on the ground floor of buildings. At the same time, attention should be paid to the isolation of transmitting and receiving equipment. In multi-storey buildings, the shielding room should be far away from elevator rooms and ventilation machine rooms. In order to save shielding materials, external electrical equipment should be installed as much as possible under possible conditions. Shielding materials play a decisive role in shielding effectiveness. Therefore, when designing shielded darkrooms, there are certain requirements and restrictions on shielding materials.
