摘要

本文分析了金属保护罩内电磁吸收体的冲击。为了提高吸波器的屏蔽效果，特别是在第一共振频率处的屏蔽效果，将吸波器置于箱体内。分析了不同的吸波板在箱体内的位置。吸收板的尺寸与外壳的壁相匹配。实验过程在半消声室中进行。考虑吸波板在不同壁面上的位置，对箱体内电磁场分布进行了TLM数值模拟。

Experimental shielding effectiveness study of metal enclosure with electromagnetic absorber inside

In this paper, the impact of an electromagnetic absorber inside a protective metal enclosure is analyzed. The absorber is put inside the enclosure in order to improve its shielding effectiveness, especially at the first resonant frequency. Different absorber's sheet positions inside the enclosure are analyzed. The absorber sheet dimensions are fitted to correspond the enclosure's walls. The experimental procedure is conducted in a semi-anechoic room. The numerical TLM simulations of the EM filed distribution inside enclosure are conducted in order to consider position of the absorber sheet on different walls.
