Application of Coating Absorbing Materials in Communication Equipment: How to Reduce Electromagnetic Interference?

With the rapid development of modern communication technology, the application of electromagnetic waves in fields such as communication, radar, and electronic devices is becoming increasingly widespread. However, while electromagnetic waves bring convenience, they may also cause problems such as electromagnetic interference and radiation. Therefore, developing coating absorbing materials that efficiently absorb and convert electromagnetic waves is of great significance for improving the electromagnetic compatibility and safety of equipment. This article will explore how coated absorbing materials can reduce electromagnetic interference, and specifically introduce Advanced Institute (Shenzhen) Technology Co., Ltd. and itsResearch Platinum Brand Coating Absorbing MaterialsApplication in this field.

1、 Basic principles of coating absorbing materials

Coated absorbing materials are materials that can absorb and convert incident electromagnetic wave energy into thermal energy or other forms of energy, thereby reducing electromagnetic wave reflection and scattering. The basic principles include the loss mechanism of electromagnetic waves, the matching of electromagnetic parameters of materials, and the design of microstructures.

1. The loss mechanism of electromagnetic waves:

   • Resistive loss: When electromagnetic waves propagate through materials, they are converted into thermal energy due to the resistance of the material.
   • Dielectric loss: Electromagnetic waves cause polarization phenomena in dielectric materials, which in turn generate heat.
   • Magnetic loss: Electromagnetic waves cause magnetization in magnetic materials, converting electromagnetic wave energy into thermal energy through hysteresis loss, eddy current loss, and other methods.

2. Electromagnetic parameter matching: Coating absorbing materials need to have good electromagnetic parameter matching characteristics, that is, the dielectric constant and magnetic permeability of the material need to match the impedance of free space to reduce the reflection of electromagnetic waves, so that electromagnetic waves can enter the interior of the material more and be absorbed.

3. Microstructure design:Coating absorbing materialThe microstructure has a significant impact on its absorption performance. By regulating the microstructure of materials, such as particle size, shape, distribution, etc., the electromagnetic parameters of materials can be optimized to improve the absorption efficiency of electromagnetic waves.

3、 Application of Coating Absorbing Materials in Communication Equipment

In communication equipment, the application of coating absorbing materials is mainly reflected in the following aspects:

1. Absorbing electromagnetic wave energy: Coating absorbing materials can absorb and attenuate the energy of electromagnetic waves incident in space. When electromagnetic waves induce and generate currents inside the material, these currents are hindered in transmission and converted into internal energy (such as thermal energy), thereby achieving the absorption and attenuation of electromagnetic waves. This process helps to reduce electromagnetic interference inside and outside communication devices.

2. Blocking noise transmission path: Coated absorbing materials can be attached to metal frames, LCD metal back covers, and other positions in communication equipment to block the transmission path of noise. By absorbing and scattering electromagnetic waves, coating absorbing materials can reduce the propagation energy and distance of electromagnetic waves, thereby reducing interference levels.

3. Optimize the internal electromagnetic environment of communication equipment: Communication equipment contains multiple electronic modules and components that generate electromagnetic radiation during operation. If these electromagnetic radiations are not effectively controlled and managed, they may interfere with each other, affecting the performance and stability of the equipment. The application of coating absorbing materials can optimize the electromagnetic environment inside communication equipment, reduce electromagnetic interference between different modules by absorbing and isolating excess electromagnetic waves, and improve the overall performance of the equipment.

4. Isolation of external electromagnetic interference: Communication equipment may be affected by various electromagnetic waves from the outside during use, which may affect the communication quality and performance of the equipment. The application of coating absorbing materials can effectively isolate the interference of external electromagnetic waves and protect the normal operation of communication equipment and communication systems.

5. Preventing sensitive information leakage: In some cases,Coating absorbing materialIt can also be used to prevent sensitive information leakage in communication devices by absorbing and isolating electromagnetic waves, reducing the possibility of information transmission through electromagnetic waves.
