吸波材料抑制电子设备机箱谐振的数值研究

Numerical Research on Absorbing Materials Restricting the Resonance of Electronic Equipments Box

本文首先介绍了吸波材料的吸收机理,同时应用有限元方法对贴有吸波材料的腔体进行了分析,并针对辐射情况,仿真了腔体在贴装吸波材料以后中心点的屏效,从中可以看出吸波材料对腔体谐振具有较好的抑制效果。

This paper firstly introduce the absorbing mechanisms of absorbing material, and then we present a analysis of cavity coated with absorbing material by finite element method, the distribution of field in cavity is simulated under the case of scattering, from which we come to a conclusion that the absorbing material has a great decay to the resonance of the cavity.
