中文摘要:
      通过改变电阻膜型超材料吸波体单元图案形状对吸波性能的影响有限,当超材料吸波体的结构单元参数一旦确定时,超材料的吸收频率和吸收强度就基本确定。但是优化电阻膜型超材料的材料参数能够改善其吸波性能。本研究从电阻膜型超材料吸波体的自身材料构成出发,分析和讨论了电阻膜方阻值、介质层的介电常数和厚度三种材料参数对超材料吸波体吸波性能的影响规律,分析了产生这种现象的机理和原因,为电阻膜型超材料吸波体的设计及优化提供参考和依据。
英文摘要:
      The effect of changing the cell pattern of the metamaterial absorbers based on resistance films on absorbing material was limited. The absorbing frequency and intensity of the metamaterial absorbers were basically determined when the structure parameters were confirmed. However, the absorbing properties can be improved by optimizing the material parameters of the absor-bers. Based on the unique structure of metamaterial absorbers, several material parameters were analyzed and discussed in this article, such as the sheet resistivity of the resistance films, the dielectric constant and thickness of the dielectric substrate. The influence of these material parameters on absorbing performance was studied, and the mechanism and reason of this phenomenon were also analyzed. This research aimed to provide a reference for the design and optimization of the metamaterial absorbers.
