Is the magnetic permeability of low permeability absorbing materials adjustable?

Low permeability absorbing materials, as a special functional material, have a wide range of applications in the field of electromagnetic compatibility (EMC), especially in electromagnetic wave isolation, reduction of electromagnetic interference, and electromagnetic radiation control. This article will explore whether the magnetic permeability of low permeability absorbing materials can be adjusted, and combine it with the research of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum brand low magnetic permeability absorbing materialProvide specific explanations.

1、 Basic characteristics of low permeability absorbing materials

The main characteristic of low permeability absorbing materials is their low magnetic permeability, which means that when electromagnetic waves pass through the material, it is not easy to form electromagnetic induction in the material. This characteristic enables the material to effectively absorb electromagnetic wave energy, reducing its reflection and transmission. Low permeability materials typically adopt special microstructures, such as dispersed conductive particles and multi-layer stacking of absorbing layers, to increase the material's ability to absorb electromagnetic waves.

In addition, low permeability absorbing materials also have certain magnetic loss characteristics. By designing the magnetization characteristics and structure of materials, they can undergo magnetic moment reversal under the action of electromagnetic waves, thereby converting the energy of electromagnetic waves into magnetic energy and thermal energy loss, achieving the absorption effect. This magnetic loss characteristic can be achieved through magnetization relaxation and magnetization reversal, thereby reducing the reflection and transmission of electromagnetic waves.

2、 Adjustability of magnetic permeability

The magnetic permeability of low permeability absorbing materials can be adjusted to a certain extent, which mainly depends on the composition, structural design, and preparation process of the material. Here are some key factors that affect the adjustability of magnetic permeability:

1. Material selection: Different absorbing materials have different absorption frequency bands and absorption capabilities. For example,ferritesCarbon based materials have good absorption performance in the high frequency range, while carbon based materials exhibit excellent performance in the low frequency range. By selecting materials reasonably, the range of magnetic permeability can be preliminarily determined.

2. Thickness and shape adjustment: by adjustingAbsorberThe thickness and shape can optimize its absorption effect. Generally speaking, increasing the thickness of the material helps to improve the absorption performance, but it also increases the cost and weight. Therefore, optimization needs to be carried out according to specific application scenarios.

3. Multi layer structure design: By adopting a multi-layer structure design and combining the advantages of different materials, the overall absorption efficiency can be significantly improved. For example, by combining high permeability materials with low permeability materials, complementary effects can be formed to adjust the overall permeability.

4. The addition of conductive agent: The addition of conductive agent can effectively improve the absorption performance of absorbing materials. Common conductive agents include conductive carbon black, metal powder, etc. Adding conductive agents can increase the conductivity and permeability of materials, thereby improving their absorption performance.

5. Preparation of composite materials: Composite materials are composed of two or more materials mixed in a certain proportion, and have excellent comprehensive performance characteristics. For example, combining graphene with polymers can significantly improve the absorption performance. Graphene, as an emerging nanomaterial, has attracted widespread attention in the field of microwave absorption.
