Radio frequency interference (RFI) and electromagnetic interference (EMI) are disturbances caused by electrical and electromagnetic fields that can disrupt the functioning of electrical and electronic equipment. Fortunately, manufacturers have developed materials that can protect against these disturbances. RFI and EMI shielding and absorbing materials are used in many fields, and have a wide range of applications.

RFI and EMI shielding materials are typically metallic materials that are designed to effectively reduce the level of interference from external sources. The higher the conductivity of the material, the more shielding it will provide. Silver and nickel are commonly used shielding materials, as they are excellent conductors of electricity and have good electrical properties. Other metals, such as copper, tin, or aluminum, can also be used for shielding. These metals are usually coated with various substances, such as plastic, to create a more durable and efficient shield.

RFI and EMI absorbing materials are used to absorb the energy from external electromagnetic fields. These materials are typically non-metallic, and are designed to absorb energy that would otherwise be reflected back towards the source. They absorb electromagnetic energy over a wide range of frequencies, and can be tuned to absorb energy at specific frequencies. Common absorbing materials include ferrites, ferroelectric ceramics, carbon nanotubes, and dielectric materials.

RFI and EMI shielding and absorbing materials are used in a wide range of applications, including aircraft, satellites, electronic assemblies, medical equipment, and consumer electronics. The materials are used to protect against incoming radio frequency signals, and also to reduce the level of interference produced by electronic components. Shielding materials are primarily used to protect against incoming signals, while absorbing materials are used to absorb the energy produced by electronic components.

The basic working principle of RFI and EMI shielding and absorbing materials is the same: to reduce the level of interference from external sources. Shielding materials absorb and deflect signals, while absorbing materials absorb and dissipate the energy. The effectiveness of the materials depends on the frequency of the signal, the material used, and the type of shielding or absorbing material used.

RFI and EMI shielding and absorbing materials are essential components of many electronic devices. They are used to protect against incoming and outgoing radio frequency signals, and reduce the level of interference from external sources. The materials are used in a wide range of applications, including aircraft, satellites, electronic assemblies, medical equipment, and consumer electronics.
