摘要/Abstract

摘要： 线状金属颗粒在复合物中会构成回路，产生较强的磁响应，这种磁响应受温度影响小.基于有效介质理论，探讨线状金属颗粒复合材料电磁响应的基本特征，优化设计适用于高温环境的、性能较好的线状钨颗粒复合微波吸收材料.

关键词: 微波吸收材料, 磁响应, 线状金属颗粒, 有效介质理论

Abstract: It is shown that various closed circuits formed by line-shaped metallic particles in composite induce great permeability. Effect of temperature on magnetic response is weak. Based upon effective medium theory,electric and magnetic response of composites containing line-shaped tungsten particles are addressed. Microwave absorbing composites are designed and optimized, which may be applied in high temperature circumstances.

Key words: microwave absorbing materials, magnetic response, line-shaped metallic particles, effective medium theory
