Abstract A multiple working mechanism metasurface (MWMM) is proposed to reduce infrared emission and the microwave reflection simultaneously. In addition, it has good oblique performance and achieves compatibility-stealth for infrared(IR)- radar. For these purposes, the first working mechanism of MWMM which is designing stacking two arrays which is ITO as an alternative without other opaque metals is for the visible transparence. The second working mechanism of MWMM which is designing a frequency selective surface (FSS) made of ITO arrays instead of other low infrared emissivity metals achieves the characteristic of IR-stealth. The third and last working mechanism of MWMM are the microwave absorption and the phase cancellation respectively to reduce reflection for microwave-camouflage. The tailored MWMM exhibited a broadband the efficiency larger than 10 dB from 7.21GHz and 18.89GHZ and low IR emissivity is about 0.3 in the region of 3-14μm with high IR-reflection over than 80% under the same region. And comparing with the simple absorber, the part-absorptive principle for infrared will reduce temperature for this MWMM under the higher conditions. This is needed urgently for IR-radar compatible-stealth application.

具有高光学透明度、低红外发射率和微波反射减少的多重工作机制超表面

摘要 为了同时减少红外发射和微波反射,提出了一种多工作机制超表面(MWMM)。此外,它还具有良好的斜向性能,实现了对红外(IR)雷达的兼容隐身。出于这些目的,MWMM 的第一个工作机制是设计堆叠两个阵列,即 ITO 作为替代,没有其他不透明金属,是为了可见透明。MWMM的第二种工作机制是设计由ITO阵列代替其他低红外发射率金属制成的频率选择表面(FSS),实现了红外隐身的特性。MWMM的第三个也是最后一个工作机制分别是微波吸收和相位抵消,以减少微波伪装的反射。定制的 MWMM 在 7.21GHz 和 18.89GHZ 范围内表现出大于 10 dB 的宽带效率,并且在 3-14μm 区域内的低红外发射率约为 0.3,在同一区域内具有超过 80% 的高红外反射率。与简单的吸收器相比,红外线的部分吸收原理将在更高的条件下降低该MWMM的温度。这是红外雷达兼容隐身应用迫切需要的。
