How to overcome the problem of excessive electromagnetic wave penetration in low permeability absorbing materials

With the development of modern technology, the application of electromagnetic waves is becoming increasingly widespread, but at the same time, it has also brought about problems of electromagnetic wave interference and excessive penetration. Especially in the fields of electronic devices, communication systems, and military equipment, excessive electromagnetic wave penetration can lead to signal interference, information leakage, and electromagnetic radiation hazards. In order to overcome these problems, Advanced Institute (Shenzhen) Technology Co., Ltd. has launchedResearch Platinum brand low magnetic permeability absorbing materialThis provides an effective solution for the protection of electromagnetic waves.

1、 The essence of electromagnetic wave penetration power

The penetration power of electromagnetic waves depends on their wavelength and frequency. The shorter the wavelength, the higher the frequency, and the higher the energy of electromagnetic waves, the stronger their ability to directly pass through objects. Electromagnetic waves with longer wavelengths are more likely to bypass obstacles and achieve "penetration" through diffraction phenomena. In practical applications, people usually focus on how to reduce the direct penetration of electromagnetic waves and avoid their interference and damage to sensitive electronic components.

2、 The mechanism of low permeability absorbing materials

Low permeability absorbing materials are a special type of materialElectromagnetic functional materialsIt has the characteristics of lightweight, temperature and humidity resistance, and corrosion resistance. It converts electromagnetic wave energy into other forms of energy (such as thermal energy) through specific mechanisms (such as resistive loss, dielectric loss, and magnetic loss), thereby achieving absorption of electromagnetic waves. These materials exhibit good absorption characteristics over a wide frequency range, making them particularly suitable for situations where electromagnetic interference and leakage need to be reduced.
