随着现代信息技术特别是微波通信技术的飞速发展,环境中存在的电磁辐射污染已经成为一个不可忽视的问题。研究表明:长期暴露在电磁辐射下容易对身体健康造成影响,且电磁辐射对电子设备的干扰也无处不在。频率1～8GHz的电磁波在日常生活中应用广泛,在军事领域,随着雷达使用频段拓宽,低频雷达波的隐身材料仍需要进一步研究和开发,所以新型低频吸波材料研究无论对人类健康还是军事隐身材料的发展都有重要意义。从吸波机理出发,综述了新型低频吸波材料的设计及研究进展,并展望了新型低频吸波材料的研究方向。
With the rapid development of modern information technology,especially microwave communication technology,electromagnetic (EM) radiation pollution in the environment has become a problem that cannot be ignored.Studies show that long-term exposure to electromagnetic radiation is easy to affect human health,and electromagnetic radiation interference on electronic equipment is everywhere.An electromagnetic wave with a frequency range of 1～8GHz is widely used in daily life.In the military field,with the broadening of the radar frequency band,stealth materials for low-frequency radar waves still need to be further researched and developed.Therefore,the research on novel low-frequency absorbing materials is of great significance to both human health and the development of military stealth materials.Based on the absorbing mechanism,the design and research progress of novel low-frequency absorbing materials were reviewed,and the research direction of these materials was prospected.
