How to balance the absorption performance and material thickness of mobile phone magnetic barrier absorbing materials?

With the continuous development and popularization of smartphones, the application of magnetic barrier absorbing materials in mobile phones is becoming increasingly widespread. This material mainly reduces unwanted electromagnetic radiation by absorbing, reflecting, or scattering electromagnetic waves, thereby protecting mobile communication systems from external interference and optimizing the electromagnetic environment inside mobile phones. This article will explore how to balance the absorption performance and material thickness in mobile phone magnetic isolation absorbing materials, and present the findings of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum brand mobile phone magnetic isolation sheet absorbing materialProvide a detailed analysis as an example.

1、 The relationship between absorption performance and material thickness

1. The variation of absorption performance with thickness

The thickness of the absorbing plate has a significant impact on its electromagnetic wave absorption performance. Within a certain range, as the thickness of the absorbing plate increases, its ability to absorb electromagnetic waves may be enhanced. However, when the thickness increases to a certain extent, the absorption performance may reach saturation, and may even slightly decrease as the thickness continues to increase. This relationship is not a simple linear relationship, but there exists an optimal thickness interval.

2. The relationship between thickness and absorption frequency band

The thickness of a waveplate is also related to its absorption frequency band. Thicker absorbing plates often have a narrower absorption band, while thinner absorbing plates may have a wider absorption band. This is because absorbing plates of different thicknesses have different absorption and reflection characteristics for electromagnetic waves, which affects the width of their absorption frequency band.

2、 Characteristics of Wave Absorbing Materials for Research Platinum Brand Mobile Phone Magnetic Plates

The research platinum brand mobile phone magnetic isolation sheet absorbing material of Advanced Institute (Shenzhen) Technology Co., Ltd. has the following characteristics:

1. High Magnetic Permeability

Research Platinum Brand Magnetic Barrier Absorbing MaterialHaving high magnetic permeability helps to concentrate magnetic field lines, prevent magnetic field diffusion, and reduce magnetic interference with other components. For example, in the vicinity of magnetic components such as speakers and earphones in devices, magnetic separators can effectively limit the magnetic field within a certain range, avoiding adverse effects on nearby antennas, circuit boards, and other components.

2. Good absorption performance

This material exhibits excellent absorption performance in specific frequency bands. In smartphones, various wireless communication frequency bands (such as Wi Fi frequency band, Bluetooth frequency band, etc.) coexist and are prone to mutual interference. The research platinum brand magnetic isolation sheet absorbing material can effectively absorb electromagnetic waves in these frequency bands, improving the overall electromagnetic compatibility of the equipment.

3. Thickness optimization

The research platinum brand mobile phone magnetic isolation sheet absorbing material achieves a balance between absorbing performance and material thickness through precise thickness design. By controlling the thickness of the material, it is possible to reduce the weight and cost of the material while ensuring the absorption performance, and improve the economy and practicality in practical applications.

3、 How to balance absorption performance and material thickness

In practical applications, balancing the absorption performance and material thickness requires comprehensive consideration of the following factors:

1. Equipment requirements

Different devices have different requirements for magnetic isolation effect. The appropriate thickness of the magnetic isolation sheet needs to be selected based on factors such as the performance parameters of the equipment, working environment, and usage requirements. Measure the strength of the magnetic field using measuring tools such as magnetometers, and select the thickness of the magnetic separator based on the measurement results.

2. Economy and practicality

Although overly thick magnetic separators can provide better magnetic isolation effects, they can also increase costs and processing difficulties. Therefore, it is necessary to choose an economically reasonable thickness of the magnetic isolation sheet while ensuring the magnetic isolation effect.

3. Surface flatness and smoothness

The flatness and smoothness of the surface of the magnetic isolation sheet have a significant impact on its magnetic isolation effect. If there are defects or contamination on the surface of the magnetic isolation sheet, it may affect its magnetic isolation effect. Therefore, it is necessary to regularly clean and maintain the magnetic separator to ensure that its surface is in good condition.

4、 Application Case of Research Platinum Brand Mobile Phone Magnetic Barrier Absorbing Material

The research platinum brand mobile phone magnetic isolation sheet absorbing material has been widely used in smartphones. For example, placing magnetic separators around the antenna can absorb stray electromagnetic radiation from other components such as batteries, processors, etc., reducing interference with the antenna signal. At the same time, it can also prevent the signal radiated by the antenna itself from interfering with other components, thereby improving the signal reception and transmission efficiency of the antenna.

In addition,Research Platinum brand mobile phone magnetic isolation sheet absorbing materialIt can also be applied to isolation in multi antenna systems to prevent signal crosstalk. Placing magnetic barriers near the camera can effectively reduce the impact of electromagnetic interference on image quality. Placing magnetic separators around the battery can absorb the electromagnetic radiation generated by the battery and prevent it from causing adverse effects on other components.

5、 Conclusion

The absorption material of mobile phone magnetic isolation sheet is of great significance in balancing the absorption performance and material thickness. By designing the thickness of materials reasonably, it is possible to reduce the weight and cost of materials while ensuring absorption performance, and improve the economy and practicality in practical applications.
