Honeycomb type absorbing materials have shown wide application prospects in multiple fields due to their unique structure and excellent absorbing performance. This article will explore the influence of different honeycomb structures on the electromagnetic wave absorption frequency range of honeycomb absorbing materials, and combine it with the research of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Honeycomb Absorbing MaterialConduct a specific analysis.

Basic Structure and Principle of Honeycomb Absorbing Materials

The design inspiration for honeycomb type absorbing materials comes from the honeycomb structure in nature. By imitating this efficient and lightweight structural characteristic and combining it with specific absorbing materials, it achieves efficient absorption and dissipation of electromagnetic waves. Its uniqueness lies in its hexagonal structure resembling a honeycomb, which not only provides excellent mechanical properties and stability, but also enables the material to generate multiple reflections and scattering during electromagnetic wave propagation, thereby increasing the opportunities for interaction between electromagnetic waves and materials.

Honeycomb type absorbing materialThe absorption principle mainly includes:

1. The function of absorbers: Absorbents in materials can convert incident electromagnetic waves into other forms of energy such as thermal energy, achieving absorption of electromagnetic waves.
2. Multiple reflections and scattering: The honeycomb structure allows electromagnetic waves to reflect and scatter multiple times inside the material, prolonging the interaction time between electromagnetic waves and absorbers, increasing the path of action, and improving absorption efficiency.
3. Impedance matching: By adjusting the impedance of the material to match the impedance of free space, the reflectivity of electromagnetic waves is reduced, allowing them to enter the material smoothly and be absorbed.

The influence of different honeycomb structures on the frequency range of electromagnetic wave absorption

1. Standard cellular structure

The hexagonal aperture size and arrangement rule of the standard honeycomb structure enable the material to have good absorption effect over a wide frequency range. Taking 3-16 GHz as an example, the absorption performance of a certain sample meets the standard of less than -10 dB, and the maximum reflection loss is about -36 dB. The carbonyl iron particles (CI) prepared by vacuum bag technology and the epoxy resin composite material added with MWCNT, using glass fiber reinforced epoxy resin as the panel material and carbon fiber reinforced epoxy resin as the bottom plate material, have a bandwidth of less than -10 dB up to 18.37 GHz and a maximum reflection loss of about -46 dB.

2. Optimized cellular structure

By optimizing the design of the honeycomb structure, the absorption performance of the material can be further improved. The optimized honeycomb structure has a larger effective thickness for incident electromagnetic waves and a wider absorption bandwidth. In the same frequency band, the reflection loss can be significantly improved. For example, in the range of 5.8-18 GHz, the reflection loss is less than -10 dB, and the maximum reflection loss is about -29 dB. This optimization typically involves adjusting the aperture size, shape, and arrangement to achieve more efficient electromagnetic wave absorption.

3. Improved honeycomb structure by electroless nickel plating

In order to further enhance the absorbing performance of the material, the method of electroless nickel plating can also be used to improve the electromagnetic properties of glass fibers. This method does not require the addition of conductive particles or metal magnetic micro powders, and only enhances the material's absorption performance through nickel plated fibers. The results show that within the frequency range of 5.8~18 GHz, the reflection loss is less than -10 dB, and the maximum reflection loss is about -29 dB. This method not only simplifies the preparation process, but also improves the overall performance of the material.
