In today's rapidly advancing technology, electromagnetic waves are everywhere, like invisible messengers, playing a crucial role in fields such as communication, radar, and healthcare. However, with the intensive deployment of electronic devices, electromagnetic wave interference and radiation problems have become increasingly prominent, becoming one of the bottlenecks restricting the development of modern technology. In this context, the Advanced Institute, with its profound scientific research capabilities and forward-looking technological vision, has successfully developed multi-layer structured high permeability absorbing materials, bringing revolutionary breakthroughs to electromagnetic wave management.

1、 Introduction: Challenges and Opportunities of Electromagnetic Wave Absorption

The absorption and shielding of electromagnetic waves have long been a major challenge in the field of materials science. Traditional absorbing materials often face problems such as limited absorption frequency band, large thickness, and heavy weight, which make it difficult to meet the urgent needs of modern electronic devices for lightweight and high-efficiency. Therefore, developing a new type of absorbing material that can effectively broaden the absorption frequency band while maintaining its lightweight characteristics has become a common goal pursued by the industry.

The core of this material lies in its intricate multi-layered structural design, where each layer plays a specific role in constructing an efficient and broadband electromagnetic wave absorption system. By precisely controlling the material composition, thickness, and arrangement sequence of each layer, comprehensive optimization of electromagnetic waves from incidence, propagation to final absorption has been achieved.

1. High magnetic permeability core layer: As the heart of the absorbing material, this layer uses special alloys or ferrite materials with high magnetic permeability, which can effectively guide electromagnetic waves into the interior of the material, reduce reflection, and lay the foundation for subsequent absorption processes.

2. Loss dielectric layer: Adjacent to the core layer is the loss dielectric layer, which utilizes the dielectric and magnetic loss characteristics of the material to convert electromagnetic wave energy into thermal energy or other forms of energy for dissipation, thereby achieving effective absorption of electromagnetic waves.

3. Matching layer and reflection layer: The outermost matching layer is responsible for adjusting the impedance of the material to match the impedance of free space, reducing the reflection loss of electromagnetic waves; The reflective layer utilizes metal or highly conductive materials to reflect electromagnetic waves that have not been fully absorbed back to the lossy dielectric layer for secondary absorption, further improving absorption efficiency.

3、 High magnetic permeability: a multiplier of absorption capacity

The high or low magnetic permeability directly affects the material's ability to guide and absorb electromagnetic waves. By adopting advanced material synthesis technology and microstructure design, the Advanced Institute has successfully increased the magnetic permeability of the material to an unprecedented height. This not only broadens the absorption frequency band of the material, but also significantly enhances its absorption intensity at specific frequencies, enabling even high-frequency electromagnetic waves that are difficult to capture to be effectively absorbed.
