作为2D超材料，由于对电磁波（EM）波的振幅，相位，极化和传播的幅度，相位，极化和传播的独特操纵，因此众所周知。但是，现有的元信息主要是为控制入射波而设计的。在此提出，同时提出了具有两个双波段发射和扩散功能的编码馈送跨表面（CFM）。锯齿形发射贴片和两个用于极化转换的弧形三角形贴片嵌套在CFM的单位单元格的共享孔径上。引入了遗传优化算法以扩散。制造并测量原型以验证提出的双重功能的CFM。实验结果与模拟数据非常吻合，该数据验证了CFM的扩散和发射。具有轻巧，紧凑和低调的CFM在隐形飞机的成像，检测和无线通信系统中具有潜在的应用。
As 2D metamaterials, metasurfaces are well known due to the distinctive manipulation of the amplitude, phase, polarization, and propagation for electromagnetic (EM) waves. However, the existing metasurfaces are mainly designed to control the incident waves. Herein, a coding-feeding metasurface (CFMS) with two functions of dual-band emission and diffusion for incidences simultaneously is proposed. The zigzag emission patch and two arc-split triangle patches for polarization conversion are nested together on a shared aperture of a unit cell for CFMS. The genetic optimization algorithm is introduced for diffusion. A prototype is fabricated and measured to validate the proposed CFMS with dual-function. The experimental results agree well with the simulated data, which verify the diffusion and emission for CFMS. The CFMS with the lightweight, compact, and low profile has the potential applications in imaging, detection, and wireless communication systems for stealth aircraft.
