NFC anti metal absorbing materials: key technology to reduce metal reflection of NFC signals

In today's digital age, NFC (Near Field Communication) technology has been widely applied in many fields, such as mobile payments, access control systems, smart wearable devices, etc., bringing great convenience to people's lives. However, when NFC technology is applied in metal environments, the reflection and interference of NFC signals by metals have become an urgent problem to be solved. Advanced Institute (Shenzhen) Technology Co., Ltd. focuses on the research and development of related materials, and its NFC anti metal absorbing materials have played an important role in solving this problem.

Challenges faced by NFC signals in metallic environments

NFC signals are essentially electromagnetic waves that generate eddy current effects when propagating in a metallic environment. When the electromagnetic waves of NFC signals are irradiated onto the metal surface, the free electrons inside the metal will undergo directional movement under the action of the electric field, forming eddy currents. These eddy currents will generate a magnetic field opposite to the original NFC signal, causing interference and reflection on the NFC signal, resulting in a significant reduction in the strength of the NFC signal, unstable signal transmission, and even data transmission errors or inability to connect, seriously affecting the normal application of NFC technology.

Working principle of NFC anti metal absorbing material

Developed by Advanced Institute (Shenzhen) Technology Co., LtdNFC anti metal absorbing materialIt is a magnetic functional material with high magnetic permeability characteristics. Its main function is to reduce or eliminate the interference and reflection of metal on NFC signals, ensuring stable and reliable data transmission.

This material typically has a high magnetic permeability real part, which can effectively bundle the magnetic flux of NFC communication antenna signals. When NFC signals propagate in a metal environment and encounter the absorbing material, the high magnetic permeability of the material enables it to guide the magnetic flux of the NFC signal, allowing the signal to bypass the metal interference area and avoid direct reflection on the metal surface. At the same time, the material maintains a low imaginary part of magnetic permeability to reduce the loss of communication signals and ensure the strength and stability of NFC signals during transmission.

Characteristics of NFC anti metal absorbing materials

1. High magnetic permeability: It can effectively bundle the magnetic flux of NFC signals, guide signals to bypass metals, and reduce reflections.
2. Low loss: While maintaining high magnetic permeability, it has a lower imaginary part of magnetic permeability, reducing energy loss to NFC signals and ensuring signal strength.
3. Stability: It can maintain stable performance under various environmental conditions, such as different temperatures, humidity, etc., ensuring the normal transmission of NFC signals.

4. Compatibility: Compatible with various NFC devices and systems, suitable for different application scenarios, whether it is smartphones, access cards, or other NFC devices, it can play its role in reducing metal reflections.
