【摘要】 吸波结构对于缩减目标的雷达散射截面积、实现目标隐身具有重要意义。实现工作频带可重构可以大大提高吸波结构应用的灵活性。本文利用石墨烯阻抗可随外界条件变化的特性,探究该材料应用于吸波结构的可能性,设计了一种工作于S/C波段的具有可重构特性的吸波结构,并将其与反射型频率选择表面结合,形成1GHz透波,4-8GHz吸波的选频吸波结构。更多还原

【Abstract】 Wave absorbing structure is of great significance for reducing the target radar cross-sectional area and achieving the target stealth.In order to improve the flexibility of the application of the absorbing structure, the reconfiguration of the working frequency band is an important method.In this paper, I used the properties of graphene,whose impedance changes with the external conditions,to explore the possibility of this material to use it in the structure of the wave absorption, and designed a structure to work in the S/C waveband with a reconfigurable ability for wave absorbing,and combined it with the reflective frequency selective surface to achieve the frequency selective microwave absorption performance,which allows 1 GHz wave through and 4-8 GHz wave absorbed.更多还原
