How to improve the stability of the absorption performance of interferometric absorbing materials with varying incident angles

Interference type absorbing materials have shown great potential in the field of electromagnetic wave absorption due to their unique interference loss mechanism. However, there is a significant challenge with such materials: their absorption performance often decreases significantly with increasing incident angle. This phenomenon limitsInterferometric absorbing materialWidely used in complex electromagnetic environments. This article will explore in depth how to improve the stability of the absorption performance of interferometric absorbing materials at different incident angles through optimized design and the adoption of new technologies. At the same time, it will be illustrated with practical cases of Advanced Institute (Shenzhen) Technology Co., Ltd. and its platinum brand products.

Basic principles and challenges of interferometric absorbing materials

The core mechanism of interferometric absorbing materials is to utilize the interference cancellation effect between surface reflected waves and bottom reflected waves to achieve effective absorption of electromagnetic waves. However, when the incident angle changes, the phase relationship and amplitude ratio between the reflected wave and the incident wave will be adjusted accordingly, resulting in a weakening of the interference effect and a decrease in the absorption performance. Therefore, how to maintain stable interference effects at different incident angles is the key to improving the performance of interferometric absorbing materials.

Strategies to enhance stability

1. Multi layer structure design:
   • By designing multi-layer structures with different electromagnetic parameters, effective matching and control of electromagnetic waves at different incident angles can be achieved. Multilayer structures can guide electromagnetic waves to propagate layer by layer within materials and attenuate layer by layer, thereby reducing the energy of reflected waves and improving the stability of absorption performance.
2. Introduction of nanomaterials:
   • Nanomaterials, due to their unique physical and chemical properties, can significantly enhance the electromagnetic loss capability of materials. Uniformly dispersing nanoparticles in interferometric absorbing materials can further enhance their ability to absorb electromagnetic waves, especially at large incident angles, where this enhancement effect is particularly pronounced.
3. Gradient structure design:
   • The design concept of gradient structure is to gradually change the electromagnetic parameters of the material, so that electromagnetic waves can gradually attenuate when propagating inside the material. This design helps to reduce the generation of reflected waves, thereby maintaining stable absorption performance at different incident angles.
4. Advanced preparation technology:
   • Adopting precision coating technology can ensureInterferometric absorbing materialThe coating is uniform and dense, reducing defects and pores inside the coating, thereby improving its absorption efficiency of electromagnetic waves. Meanwhile, by optimizing the microstructure and electromagnetic parameters of the material through processes such as heat treatment, its absorption performance is further enhanced.
