| 摘 要： | 在微波频段,频率选择表面中的金属部分通常被认为是完全电导体,但是在红外波段,金属通常具有有限大的色散的复值电导率.因此首先建立了包含有金属色散电磁性质的材料模型,即金属部分被看作具有合适介电常数的介质层,然后采用时域有限差分法研究它在红外波段的特性并给出了场更新方程.最后与文献的结果进行对比,验证了方法的有效性,并研究了不同金属种类对红外频率选择表面谱域性质的影响.

| Abstract: | Many metals used in Frequency selective surfaces(FSSs) behave essentially as perfect electric conductors for microwaves,but possess finite,dispersive,complex valued conductivity at higher frequencies,such as infrared.Material model including dispersive electromagnetic properties of metals is established,which treat metal as medium lays that possess appropriate permittivity.Field updating equations are also derivate.Validate it by comparing results to previous document results,and investigate the effect of d... |
