中文摘要	设计了一个由金属谐振单元、FR4基板和金属背板构成的超材料吸波体,通过数值仿真软件对该吸波体在2~8GHz范围内的S参数以及吸收率特征进行了计算;对这个模型进行了取轮廓化的处理,通过计算发现这种处理对其谐振吸收基本上没有影响;在此基础上,通过在这个轮廓模型中加入其他谐振单元,实现了双频带范围的微波衰减吸收。通过激光刻蚀的方法,对所设计的模型进行了实验验证,发现计算结果和实验结果有很好的一致性,这就验证了超材料轮廓法拓宽吸波材料的技术思路,为宽频带超材料吸波体的研究提供了一个可行的技术途径。; A metamaterial absorber was designed which is constituted of metal resonance unit,FR4 substrate and metal backing.The S parameters and reflectivity characteristics were calculated by means of the numerical simulation method in 2-8GHz.The model was outlined and calculated again,the results show that the contour treatment,on the whole,has no effect on the resonance frequency.Based on this,dual band microwave attenuation absorption is achieved by virtue of combining other resonant metamaterial unit into the former unit contour,which provides an excellent technological approach to further study the broadband microwave absorbing materials.The samples of all the simulation model are verified by laser etching technology and the calculation results match very good with the experimental results,which verifies the technological thinking of metamaterials contour broadening the wave absorbing materials and paves a good path to broaden the bandwidth of microwave absorbing.
