【摘要】 基于人工电磁超材料对电磁波的调控作用。设计、研究并且加工一款具有宽入射角且极化独立的超材料吸波器。该超材料吸波器具有重量轻、厚度薄、容易加工、成本低的特点。仿真与实验结果表明该吸波器在4.18-4.252GHz、8.068-8.188GHz以及11.736-11.9GHz频段内吸波率高达90%以上,在18.672-18.84GHz频段内吸波率在75%以上,在13.532-13.728GHz频段内吸波率在50%以上。另外,研究表明对入射角在0°～60°范围内变化的TE模式和TM模式的电磁波该吸波器仍然具有较好的吸波特性。更多还原

【Abstract】 Based on the regulation effect of artificial electromagnetic metamaterials on electromagnetic wave,a metamaterial wave absorber with wide incidence Angle and independent polarization was designed,studied and fabricated. The metamaterial wave absorber is characterized by light weight,thin thickness,easy processing and low cost. The results of simulation and experiment show that the absorbers can absorb more than90% at 4. 18-4. 252 GHz,8. 068-8. 188 GHz and 11. 736-11. 9 GHz. The absorbers are more than 75% in 18. 672-18. 84 GHz and more than 50% in 13. 532-13. 728 GHz. In addition,the study shows that the absorber still has good absorbing characteristics for TE mode and TM mode with incident angle varying from 0° to 60°．更多还原
