论文摘要
由纳米层的材料堆栈组成的无光刻元图不仅具有吸引力，这不仅是由于其光学特性而具有吸引力，而且还因为制造简单性和基于此类结构的设备的成本降低。我们在中红外（MIR）波长范围内使用工程电磁吸收展示了多层跨表面。通过实验吸收和热辐射测量结果以及有限的差异时间域（FDTD）数值模拟，薄薄的Sio $ _2 $和SI膜的表征夹在两个AU层之间。比较多层元面的光学性质的实验和仿真数据显示了吸收器/发射极应用的指南。
Lithography-free metasurfaces composed of a nano-layered stack of materials are attractive not only due to their optical properties but also by virtue of fabrication simplicity and cost reduction of devices based on such structures. We demonstrate a multi-layer metasurface with engineered electromagnetic absorption in the mid-infrared (MIR) wavelength range. Characterisation of thin SiO$_2$ and Si films sandwiched between two Au layers by way of experimental absorption and thermal radiation measurements as well as finite difference time domain (FDTD) numerical simulations is presented. Comparison of experimental and simulation data of optical properties of multilayer metasurfaces show guidelines for the absorber/emitter applications.
