Sound absorption structures, as an effective approach to reducing sound radiation, have always received extensive attention in the engineering of vibration and noise reduction. In this work, a novel compact multifunctional metastructure is proposed for both low-frequency broadband excellent crash energy dissipation. Cavity resonators with internally extended tubes (CRIET) hexagonal honeycomb configuration were selected unit components. An optimization method was against degradation from...
The implementation of thin structure for broadband microwave absorption is challenging due to the requirement impedance match across several frequency bands and poor mechanical properties. Herein, we demonstrate a carbon fiber (CF) reinforced flexible hierarchical metastructure (HM) composed lossy materials including carbonyl iron (CI), multiwall nanotube (MWCNT), silicone rubber (SR) with thickness 5 mm optimal concentration selected from 12 formulas. Optimization periodical unit size...
Abstract Origami structures offer valuable applications in many fields, ranging from metamaterials to robotics. The multistable characteristics of origami have been pursued for acquiring unique reconfigurable features. For achieving this goal, an unusual polymeric tristable structure is demonstrated using a classic square‐twist configuration. By manipulating both material properties and geometric parameters the heteropolymer structures, design principle tailoring configuration established...
Abstract Smart structures with manipulatable properties are highly demanded in many fields. However, there is a critical challenge the pursuit of transparent windows that allow optical waves (wavelength µm–nm) for transmitting while blocking microwave cm) terms absorbing electromagnetic energy, specifically meeting frequency requirement 5th generation (5G) mobile networks. For fundamentally establishing novel structures, here, new polymeric aqueous gels as both optically materials and...
High quality Al and CuO nanowries are fabricated by simply heating the Cu samples in air. Although experimental operations stress-induced migration processes quite similar, causes of driving forces growth mechanism completely different. For nanowires, force is determined to be compressive stresses caused thermal expansion mismatch between film Si substrate, proposed extrusion atoms from bases nanowires (EAFB). formation oxide layers, molecules on surfaces (FOOS). The direct observations both...
An integrated modeling framework coupling the discrete element method for powder spreading, finite volume bed melting, and an extended cellular automaton grain structure evolution during solidification is proposed. In this framework, initial of both substrate metal powders can be taken into account used to capture epitaxial competitive growth.

Abstract Tunable radar stealth structures are critical components for future military equipment because of their potential to further enhance the design space and performance. Some previous investigations have utilized simple origami as basic adjusting but failed achieve desired broadband microwave absorbing characteristic. Herein, a novel double‐broadband switchable grid structure has been developed with actuators inflatable Kresling structures. Geometric constraints derived endow bistable...
