本文提出了一种新型的双层电磁吸振器。该吸波器由一层有耗左手材料吸波层和一层由无耗右手材料构成的阻抗匹配层组成。结果表明，在7 GHz ~ 13 GHz频率范围内，反射损耗小于-20dB。通过调制右手材料的介电常数，也可以获得窄频带电磁吸波体的功率衰减达到-50dB。此外，整个吸波结构的厚度仅为2 mm，这在一些实际应用中特别有帮助。研究结果对新型吸波材料的精确设计和隐身技术的实用化具有参考意义。
New double-layered electromagnetic absorbers are presented in this paper. The new absorbers composed of one lossy left-handed material absorbing layer and one impedance matching layer consisted of lossless right-handed material. It is indicated that the reflection loss of below −20dB can be obtained in the frequency range 7GHz–13GHz. Power attenuation achieving −50dB of narrow frequency band electromagnetic absorbers can also be obtained by modulate permittivity of right-handed material. Furthermore, the thickness of the whole absorbing structure is only 2mm, which is particularly helpful in some practical applications. The presented results are of reference significance for accurate design of the new electromagnetic absorbers and of practical prospects for stealth technology.
