How to reduce electromagnetic interference in the application of coated absorbing materials in communication equipment?

In modern communication equipment, electromagnetic interference (EMI) is an inevitable problem that can cause signal distortion, reduced transmission rates, and even equipment failures. In order to effectively reduce electromagnetic interference and improve the performance and stability of communication equipment, the application of coating absorbing materials is gradually receiving attention. Produced by Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Coating Absorbing MaterialsWith its excellent performance, it plays an important role in communication equipment. This article will explore how coated absorbing materials can reduce electromagnetic interference in communication devices.

The mechanism of action of coating absorbing materials

Coating absorbing materials mainly reduce electromagnetic interference by absorbing electromagnetic wave energy. Its mechanism of action includes the following aspects:

Dielectric loss

The polar groups inside the coating absorbing material will polarize under the action of electromagnetic waves, and the energy loss during the polarization process will convert the electromagnetic wave energy into thermal energy, thereby reducing the propagation of electromagnetic waves.

Hysteresis loss

For coating absorbing materials containing magnetic materials, electromagnetic waves can cause the rearrangement of magnetic domains inside the material, resulting in hysteresis losses during the magnetic domain flipping process, further absorbing electromagnetic wave energy.

reflection loss

The surface structure and composition of coating absorbing materials can change the reflection characteristics of electromagnetic waves, causing some electromagnetic waves to undergo reflection loss on the material surface and reducing the electromagnetic wave energy entering the interior of the equipment.

Transmission loss

Coated absorbing materials can also cause multiple reflections and refractions of electromagnetic waves inside the material, prolonging the propagation path of electromagnetic waves, increasing transmission losses, and reducing the penetration ability of electromagnetic waves.
