How to evaluate the absorption bandwidth and absorption intensity of ultra-high permeability absorbing materials?

Absorbing materials are designed to reduce the electromagnetic energy reflected back into the environment, thereby lowering the radar cross-section or improving the electromagnetic compatibility of the system. For absorbing materials, their absorption bandwidth (i.e. the effective operating frequency range) and absorption intensity (i.e. the absorption efficiency at a given frequency) are important parameters for measuring their performance. This article will explore two performance evaluation methods and demonstrate themResearch Platinum brand ultra-high magnetic permeability absorbing materialThe uniqueness of it.

Assessment of absorption bandwidth

Testing device and method

To evaluate the bandwidth of absorbing materials, a vector network analyzer (VNA) combined with a microwave anechoic chamber is commonly used for measurement. The sample was placed in a standard testing environment and the changes in reflection coefficient were observed by sending electromagnetic waves of different frequencies. Based on the curve of reflection coefficient changing with frequency, the effective operating frequency range of the material can be determined.

The advantages of researching platinum brand materials

The research platinum brand ultra-high permeability absorbing material produced by Advanced Institute (Shenzhen) Technology Co., Ltd. exhibits excellent absorption characteristics over a wide frequency range. This material can provide significant absorption in the high frequency range of GHz and has a flat response curve, which means it has stable absorption ability over a wide frequency range.

Assessment of absorption intensity

measuring principle

The absorption intensity can be quantified by calculating the reflection loss (RL) or insertion loss (IL). When electromagnetic waves encounter absorbing materials, a portion of the energy is absorbed and converted into thermal energy, while the remaining portion undergoes reflection or transmission. The greater the reflection loss, the higher the absorption efficiency of the material.

experimental result

Experiments have shown that,Research Platinum brand ultra-high magnetic permeability absorbing materialA reflection loss of over 20dB can be achieved within the target frequency band, indicating that at least 99% of the incident electromagnetic wave energy is absorbed by the material. In addition, the material also exhibits good thickness dependence, maintaining efficient absorption performance even in thinner application scenarios.
