本文的目的是提出用铁氧体粉末和不锈钢粉末制成的层合型磁性木材可以作为室内电磁波吸波材料的合适质量的木建筑材料。吉赫兹频段的实验结果表明，体积分数为20%，不锈钢与铁氧体粉末的内部比为2：3，磁层厚度为4.0 mm的层状磁性木材在2.62 GHz处的电磁波吸收特性为45.18分贝。该层合板可用于主要使用2.4 GHz频段的室内无线局域网的抗无线电干扰。(C)2009年美国物理研究所。[DOI：10.1063/1.3056403]
The purpose of this paper is to propose that a laminated-type magnetic wood using ferrite powder and stainless steel powder can serve as a wood building material of suitable quality for an indoor electromagnetic wave absorber. The experimental results for the gigahertz frequency band show that the laminated-type magnetic wood which has volume content ratio of 20 vol%, an inside ratio of stainless steel to ferrite powder 2:3, and a thickness of magnetic layer 4.0 mm has an electromagnetic wave absorption characteristic of 45.18 dB at 2.62 GHz. This laminated board can be used to prevent radio interference for indoor wireless LANs, which mainly use the 2.4 GHz frequency band. (C) 2009 American Institute of Physics. [DOI: 10.1063/1.3056403]
