Shielding and absorption materials are used in many everyday items, from consumer electronics such as cell phones to major military systems. Shielding materials are used to block out external electromagnetic fields, while absorbing materials absorb electromagnetic energy. In the case of RF and EMF shielding and absorption materials, the materials involved play an important role in reducing interference and maintaining performance. This article will discuss the application fields and working principles of FFAM201*1, a type of shielding and absorption material.

FFAM201*1 is a conductive fabric-faced composite material that consists of two layers. The first layer is an outer layer of expanded polyethylene foam, while the second layer is a conductive fabric with excellent conductivity and fabric flexibility. FFAM201*1 is designed to effectively protect against radio frequency interference (RFI) and electromagnetic interference (EMI). The composite material can effectively block, reflect or absorb radio waves, and is used in a variety of electronic and military applications, due to its low thickness and high shielding effectiveness.

In terms of application fields, FFAM201*1 can be used for applications that require good shielding efficiency, such as indoor mobile phone base stations, radio wave propagation chambers, and communication centers. The material can also be used to effectively reduce the signal of mobile phones and other communication equipment. Additionally, FFAM201*1 can be used in medical applications such as MRI machines and X-ray machines, as well as for the shielding of electric cables in automotive and industrial applications.

As for FFAM201*1\'s working principle, it relies on the Faraday-Shield-Effect (FSE). When an external electromagnetic field is incident on this material, the electronic field produced in the metal fabric interferes with the external field, and this interference reduces the magnitude of the original field. This means that the FFAM201*1 shielding and absorption material acts as a Faraday shield, diverting the incident electromagnetic field away from the protected object. The effectiveness of the shielding is based on the properties of the material, such as its thickness, density, and conductivity.

By taking advantage of the Faraday-Shield-Effect, FFAM201*1 is able to achieve high shielding performance. The material has been tested in a variety of industry standards tests, and the results showed excellent shielding performance. The material has very low loss in frequency ranges up to 18GHz, and is compatible with a variety of plating and coating processes. With its excellent shielding performance and ease of use, FFAM201*1 is an ideal shielding and absorbing material for various applications.

In summary, RF and EMF shielding and absorption materials play an important role in electronic and military systems, as they are necessary for ensuring performance and protection. FFAM201*1 is a type of shielding and absorption material that has excellent shielding performance and remains popular in applications that require RFI and EMI shielding. The material works by taking advantage of the Faraday-Shield-Effect, which allows it to effectively block, reflect, or absorb external electromagnetic fields.
