- 摘要:
- 设计一种基于闭口圆环的多波段超材料吸波器,该结构由圆环基本构成。分析了不同同心圆环的个数,以及同时依次减小圆环的宽度对结构吸收电磁波的影响。结果表明,随着圆环个数的增加,该结构多个吸收峰的吸收率也增加,在4个同心圆环结构中,有2个吸收峰的吸收率达到了86.6%,并且在波长为3532 nm及4206 nm处,吸收率分别达到了94.3%和98.6%。该结构可以应用于红外波段的多频段吸收。
- Abstract:
- A multi-band ultrafine material absorbing device based on closed-mouth ring is designed. The structure is composed of the basic composition of the ring, and the number of different concentric rings is analyzed, and the influence caused by the width of the ring on the absorption of electromagnetic waves in the structure is reduced in turn. The results show that with the increase of the number of rings, the absorption rate of multiple absorption peaks of the structure is also increasing, and in four concentric ring structures, the absorption rate of two absorption peaks reaches 86.6%, and at the wavelength of 3532 nm and 4206 nm, the absorption rate reaches 94.3% and 98.6% respectively. The structure can be applied to multi-band absorption in the infrared band.
