摘要

小型化超材料吸波器的设计基于改进的闵可夫斯基分形结构。所提出的吸波器由M-闵可夫斯基分形结构组成，其顶层蚀刻在介质衬底上，下层为金属板。模拟结果表明，该超材料吸波器具有双频吸收峰，具有较高的吸光度(>99%)。吸收器对极化不敏感，并且对于TE和TM模式具有广角(高达600度)的入射波特性。与闵可夫斯基分形结构相比，该吸波器可以减小吸收响应带，进一步实现微型化。

A novel miniaturized metamaterial absorber based on the modified Minkowski fractal structure

The design of miniaturized metamaterial absorber is based on the modified Minkowski(M-Minkowski) fractal structure. The proposed absorber is composed of M- Minkowski fractal structure in the top layer etched on dielectric substrate with the lower metal plate. The simulated results indicate that the metamaterial absorber has dual-band absorbing peaks with high absorptivity (>99%). The absorber is insensitive to polarization and has a wide angles(upto 60o) characteristic of incident waves for both TE and TM mode. The proposed absorber can reduce the absorption response bands and further implement miniaturization comparing with the Minkowski fractal structure.
