Radio frequency interference (RFI) and electromagnetic interference (EMI) are a big problem in today\'s increasingly modern world. These kinds of interference can cause advanced systems to malfunction and also cause serious health issues. To combat these issues, shielding and absorbing materials have been developed in order to block or dissipate the energy from the source. One of the most popular materials used for shielding and absorbing is 21135173 application field and working principle.

21135173 application field and working principle is a multi-layer dielectric material usually consisting of a layer of high temperature, fire-retardant polyimide film. The polyimide film has a dielectric constant of 4.5. On top of the polyimide, a thin layer of metal, usually nickel, is applied. This thin metal layer has a higher electrical conductivity than the polyimide layer. Finally, an oxidized aluminum layer is applied to the top to provide additional shielding.

The 21135173 application field and working principle is primarily used in RFI and EMI shielding applications. It can be used in both indoor and outdoor installations in applications such as military radar and satellite communications systems, wireless data systems, Wi-Fi systems, cellular networks, and more.

The 21135173 application field and working principle is able to provide both RFI and EMI shielding due to its multi-layering. The polyimide layer is designed to protect against low to mid frequency interference. The metal layer provides electrical conductivity that prevents the higher frequency interference up to 6 GHz. And finally, the aluminum layer is designed to provide shielding against the highest levels of interference up to 10 GHz.

The 21135173 application field and working principle also has the advantage of being able to absorb RF energy instead of just reflecting it. This helps to reduce any potential interference and makes it more effective against higher frequency interference. In addition, the 21135173 application field and working principle is fire-retardant, making it safe to use in many indoor and outdoor installations.

In conclusion, 21135173 application field and working principle is an effective material for both RFI and EMI shielding and absorbing. It can reduce interference in advanced systems and also helps to protect the people using them. It has the added advantages of being fire-retardant and capable of absorbing RF energy. The 21135173 application field and working principle makes it an ideal choice for many applications.
