摘　　要：研究了一种基于Salisbury屏的微波吸收材料，提出了一种具有Minkowski分形特征、表面加载阻抗的双方环形电磁带隙结构的吸波材料。该种材料具有薄、轻、吸收频带范围宽的优点，且吸波深度深于同等条件下没有分形特征的吸波材料。Microwave absorber based on Salisbury screen was studied and a novel EBG structure absorber was discussed. The EBG patch is a Minkowski fractal characterized double-square metal loop with lumped resistance loaded on the surface. Analysis indicated that the introduction of fractal characteristic helps in absorbing more incident wave.
