中文摘要:
      超材料具有传统材料所不具备的超常物理性质,对电磁场、声场等物理场可以实现自由调控。设计了一种由多尺寸的亥姆霍兹共振器和多尺寸的金属谐振结构组成的宽频吸声兼容电磁吸波的多功能超材料,实现了对声波和电磁波的宽频双吸收。仿真结果表明:文中提出的超材料在690~927 Hz范围内具有0.8以上的高吸声系数,在9.11~11.10 GHz范围内对微波具有0.8以上的吸收系数。所提出的多功能超材料对于声波及电磁波均具有宽频、高效的吸收作用,在噪声污染防治和电磁防护方面有潜在的应用价值。
英文摘要:
      Meta materials demonstrate a series of unique properties in which natural materials do not have, and these properties have powerful manipulations to electromagnetic field, acoustic field and other physical fields. Being capable of absorbing sound wave and electromagnetic wave in broadband range, a multifunctional meta material composed of the multi sized Helmholtz resonators and multi sized metal resonators, is designed. The results show that the device could achieve an acoustic coefficient of more than 0.8 in the 690~927 Hz region and a microwave absorption over 80% in the 9.11~11.10 GHz range. The multifunctional metamaterials proposed are capable of absorbing both acoustic and electromagnetic waves with broadband and high efficiency and have potential applications in the aspects of noise pollution prevention and electromagnetic protection.
