How to overcome the problem of excessive electromagnetic wave penetration in thin film absorbing materials

With the rapid development of science and technology, the application of electromagnetic waves in both civilian and military fields is becoming increasingly widespread. However, the interference and radiation problems caused by electromagnetic waves are becoming increasingly prominent. In order to overcome the problem of excessive electromagnetic wave penetration, thin film absorbing materials have emerged and shown wide application prospects in fields such as stealth technology, electronic countermeasures, and electromagnetic compatibility. This article will explore how thin film absorbing materials can overcome the problem of excessive electromagnetic wave penetration, and specifically introduce the technology of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Thin Film Absorbing Materials.

Working principle of thin film absorbing materials

Absorbing materials refer to materials that can absorb and attenuate electromagnetic waves projected onto their surfaces, and convert their electromagnetic wave energy into thermal energy to dissipate or make electromagnetic waves disappear due to interference. Thin film absorbing materials have significant advantages in electromagnetic wave absorption due to their lightweight, flexibility, and ease of processing. These materials convert electromagnetic energy into thermal energy through mechanisms such as resistive loss, dielectric loss, and magnetic dielectric loss, thereby achieving efficient absorption.

Challenges faced by thin film absorbing materials

Although thin film absorbing materials have many advantages, their absorbing properties may change in practical applications, especially when the material is on a curved surface. Bending may cause changes in the crystal structure, grain boundaries, and defects of materials, thereby affecting their absorption performance. In addition, bending may also affect the impedance matching and attenuation conditions of the material, leading to a decrease in absorption performance.
