Technical exploration of reducing surface resistance and electromagnetic wave reflection using thin film absorbing materials

Thin film absorbing materials have been widely used in fields such as electromagnetic protection, stealth technology, and electromagnetic compatibility due to their high efficiency, thinness, and ease of processing. However, the surface resistance of materials is one of the key factors affecting electromagnetic wave absorption and reflection performance. This article will explore how to reduce the reflection of electromagnetic waves by reducing the surface resistance of thin-film absorbing materials, and specifically introduce the advanced technology of Advanced Institute (Shenzhen) Technology Co., LtdResearch Platinum Brand Thin Film Absorbing MaterialsApplication in this field.

Basic principles of thin film absorbing materials

Thin film absorbing materials achieve efficient absorption of electromagnetic waves by combining absorbing materials with thin film technology. This type of material has the characteristics of wide absorption bandwidth, strong absorption capacity, light weight, and thin thickness. They can efficiently absorb and convert electromagnetic waves over a wide frequency range, thereby reducing their reflection and scattering.

Methods to reduce surface resistance

1. Impedance matching

A good absorbing material should have a certain impedance matching with air, so that electromagnetic waves can be absorbed and attenuated to the maximum extent when incident on the surface of the material, thereby reducing reflection. By adjusting the electromagnetic parameters of the material, such as dielectric constant and magnetic permeability, impedance matching can be achieved, thereby reducing reflectivity.

2. Special processing techniques

The use of microwave heating technology can significantly improveAbsorberThe performance of the material is improved by reducing its reflectivity to enhance its absorption effect. In addition, special treatment of the surface of absorbing materials, such as etching, spraying, or deposition, can alter their surface morphology and electromagnetic properties, helping to reduce interface reflection.

3. Choose appropriate substrates and coatings

Choosing a substrate with appropriate electromagnetic parameters, such as materials with low dielectric constant and low loss characteristics, can help reduce interface reflection. Coating the substrate with a coating with excellent absorbing properties can further reduce interfacial reflection. The thickness and electromagnetic parameters of the coating should be optimized according to specific requirements.
