New 5G communication materials appear! Absorbing materials make signal transmission smoother and speed doubled!

A common method is to use multi-layer structured absorbing materials, and by designing the thickness and material properties of different layers, the absorbing materials can have ideal absorption performance in different frequency bands. For example, a thick absorbing material can be used as the base layer to absorb electromagnetic waves in lower frequency bands; Then add a thin layer of absorbing material on top of the base layer to absorb electromagnetic waves in higher frequency bands. Through this layered design, it is possible to achieve effective absorption of absorbing materials in different frequency bands.

Another method is to use composite absorbing materials. Composite absorbing materials are generally made by mixing different types of absorbing materials in a certain proportion. Different types of absorbing materials have different absorption bands, and through reasonable mixing ratios, composite absorbing materials can have a wider absorption band. In addition, composite absorbing materials can also combine the advantages of various absorbing materials, improving absorption strength and absorption bandwidth.

Another method is to use porous absorbing materials. Porous absorbing materials have lower density and wider absorption frequency band. This is because porous structures can provide more interfaces, increase the propagation path of electromagnetic waves in the material, and thus improve the absorption effect. Meanwhile, the porous structure can also reduce the mass of the material, making the absorbing material thinner and lighter.

In addition to the above methods, the development of some novel absorbing materials has also brought new hope for expanding the absorption frequency band. For example, metal organic framework materials (MOFs) developed in recent years have great potential for absorbing waves. MOFs have highly tunable and controllable chemical structures, and their absorption performance can be optimized by adjusting their composition and structure. In addition, nanomaterials such as graphene and carbon nanotubes are widely used in the research of absorbing materials, which have excellent absorbing properties and controllability.

In summary, with the development of communication technology, the requirements for the absorption frequency band of absorbing materials are becoming increasingly high. In practical applications, methods such as multi-layer structures, composite materials, porous materials, etc. can broaden the absorption frequency band of absorbing materials and improve absorption intensity and bandwidth. In addition, researching novel absorbing materials is also an important way to broaden the absorption frequency band. I believe that with the continuous advancement of technology, more efficient absorbing materials will emerge, providing better solutions for applications such as 5G communication.
