Electromagnetic Wave- Absorbing Materials: Fundamentals and Applications intro-duces the fundamentals and basic concepts of the mainstream electromagnetic wave absorption materials, including MOF- derived materials, MXene- derived materials, and high- entropy materials.
In addition, it will be of great value to those directly involved in industrial sectors related to electromagnetic wave absorption materials, as well as researchers in materials science, materials chemistry, nanomaterials, and other electromagnetic materials fields.
As a result, an exceptional EM absorption performance with a minimum RL value of −53.6 dB and an effective absorption bandwidth up to 6.0 GHz (10.4–16.4 GHz) under a thickness of 2.5 mm could be achieved. Table 3. Permeability and EM absorption performance of magnetic materials–based EM absorber. Fig. 8.
Guided by the above analysis, a desirable EM absorption material should satisfy the following aspects: i) a strong absorption intensity (commercial standard, RL ≤ - 10 d B); ii) a broad effective absorption region; iii) thin thickness; iv) low–cost, low density and good chemical stability; v) low filling ratio.
Considering that the EM absorption materials are often covered on the surface of metal plane, the original transmitted EM waves would be reflected from the surface of metal plane and lead to a second absorption and reflection , . The excellent EM absorbing materials requires a strong absorption and negligible reflection.
To achieve this goal, the used EM materials need to feature a frequency–selection ability; meaning that they not only can absorb unwanted EM waves, but also allow for a good signal translation between two devices . In this regard, a very weak absorption value in a specific band is necessary, along with a strong absorption in other bands.
