0.625-5-CN3490 RF/IF and RFID

RFI and EMI shielding and absorbing materials are typically used to protect electronic circuits from interference from potential undesired electro-magnetic radiation sources. 0.625-5-CN3490 is an example of such material. It is composed of thermally-stable concentric rings of copper and nickel, produced by an electroforming process. The product boasts very low impedance and ampere loss with superior flexibility and elasticity.

The 0.625-5-CN3490 application field is primarily in aerospace and defence systems. The product is generally used in military airborne platform applications, primarily for the mitigation of Radar Interference systems (RIS). As radar absorber, it helps to reduce Radar Cross-Section (RCS) and also for electromagnetic compatibility (EMC) applications. It can also be used in commercial as well as ground-based systems where light shielding and EMI/RFI protection is required.

The working principle of 0.625-5-CN3490 is based on its absorptive and reflective properties. As far as absorptive properties are concerned, the material consists of multiple layers of concentric circles of different thicknesses, each of them is composed of a different metallic alloy. The concentric circles are arranged in such a way that the impedance of a given layer increases with the distance from the center. Thus, it is able to absorb and attenuate the incident electromagnetic wave. The material also has good reflective properties, in which the reflected signal is send back in the same direction from which it came. This helps in preventing the electromagnetic waves from entering the system.

In conclusion, 0.625-5-CN3490 is an effective RFI/EMI shielding and absorbing material. In particular, it has been utilized in military aerospace applications to reduce RCS and electromagnetic compatibility issues. The working principle of 0.625-5-CN3490 relies on its absorptive and reflective properties, which allow it to absorb and attenuate the incident wave and also prevent the wave from entering the system.
