| 1 | Selective thermal emission and infrared camouflage based on layered media显示文摘Infrared camouflage based on artificial thermal metasurfaces has recently attracted significant attention.By eliminating thermal radiation differences between the object and the background,it is possible to hide a given object from infrared detection.Infrared camouflage is an important element that increases the survivability of aircraft and missiles,by reducing target susceptibility to infrared guided threats.Herein,a simple and practicable design is theoretically presented based on a multilayer film for infrared stealth,with distinctive advantages of scalability,flexible fabrication,and structural simplicity.The multilayer medium consists of silicon substrate,carbon layer and zinc sulfide film,the optical properties of which are determined by transfer matrix method.By locally changing the thickness of the coating film,the spatial tunability and continuity in thermal emission are demonstrated.A continuous change of emissive power is further obtained and consequently implemented to achieve thermal camouflage functionality.In addition,other functionalities,like thermal illusion and thermal coding,are demonstrated by thickness-engineered multilayer films. | Qingxiang JI Xueyan CHEN Vincent LAUDE Jun LIANG Guodong FANG Changguo WANG Rasoul ALAEE Muamer KADIC | 2023 | Chinese Journal of Aeronautics2023，36，3： | 0 |
| 2 | 具有类roton色散关系的立方对称声学超材料显示文摘我们之前的工作表明,声学超材料中的非局部相互作用会导致极不寻常的类roton色散关系,即色散曲线存在局部极小值,与超流体液氦-4类似.然而,这种行为仅限于一个或两个声传播方向.在这里,我们设计了一种三维立方对称声学超材料,沿三个正交方向具有非局部相互作用.有限元计算表明超材料在三个正交方向具有类roton行为,但其行为远非各向同性.有限元结果与半解析模型结果吻合良好.相应的实验正在探索中,由于需要密集而复杂的三维声学管道,实验要求较高. | 王珂 陈毅 Muamer Kadic 王长国 Martin Wegener | 2023 | Acta Mechanica Sinica2023，39，7： | 0 |
| 3 | 滑动反射对称声子晶体界面:主题变化显示文摘节点可以在晶体界面处使用滑动反射对称性人工合成.这一特性首次在半晶格常数滑行第一个布里渊区(波数k=±π=a,a表示晶格常数)的X点方形晶格声子晶体中得到证明.在这里,考虑四分之一晶格常数滑动反射对称性,节点可以移动到Γ点(k=0).应用沿x轴连续分级的过程进一步表明条带结构基本不受影响.特别是拓扑界面波存活在滑动反射对称性仅在分级界面周围局部有效的情况下.总之,滑移位错会影响到几排晶格距离,以恢复为明显的周期性晶体. | Vincent Laude Julio Andrés Iglesias Martínez Nicolas Laforge Muamer Kadic Emil Prodan | 2023 | Acta Mechanica Sinica2023，39，7： | 0 |
