【摘要】 本文提出了一种超宽带大角度三维超材料吸波体,由三维垂直电阻膜贴片结构和底部电阻膜结构组成。该超材料吸波体在2-78 GHz内具有190%超宽的低反射带宽,在TM极化条件下保持70°以上的大角度稳定性。垂直三维结构能够在入射电磁波的激励下同时产生多种驻波模式,底部电阻膜结构起到独立拓宽带宽的作用。该三维超材料吸收体在隐身、成像和雷达探测等领域具有潜在的应用。更多还原

【Abstract】 In this paper, an ultra-wideband large-angle three-dimensional metamaterial absorber is proposed, consisting of a three-dimensional vertical resistive film patch structure and a bottom resistive film structure. The metamaterial absorber has an ultra-wide low reflection bandwidth of190% in the range of 2-78 GHz, and maintains a large angular stability of more than 70° under TM polarization conditions. The vertical 3D structure is capable of generating multiple standing wave modes simultaneously under the excitation of incident electromagnetic waves, and the bottom resistive film structure acts as an independent bandwidth broadener. The 3D metamaterial absorber has potential applications in stealth, imaging and radar detection.更多还原
