Study on “Metamaterial” Structural Absorbing Composite Technology

open access: yesCailiao gongcheng, 2017
The process technology and the mechanical and electrical properties of the "metamaterial"structural absorbing composites were studied, in which metal periodic structure units were produced on the organic carrier film and then combined with medium ...

CMOS compatible metamaterial absorbers for hyperspectral medium wave infrared imaging and sensing applications [PDF]

open access: yes, 2018
We experimentally demonstrate a CMOS compatible medium wave infrared metal-insulator-metal (MIM) metamaterial absorber structure where for a single dielectric spacer thickness at least 93% absorption is attained for 10 separate bands centred at 3.08, 3 ...

Twin Mechanical Metamaterials

open access: yes, 2021
By mimicking the geometrical relation of nano-twin crystals, we propose novel architected twin mechanical metamaterials (TMMs), which can impede local shearing band formation under external loading, thus avoiding global catastrophic failure. The effects of twin-space and twin angle on the mechanical performance of TMMs were also explored, such as ...

King post truss as a motif for internal structure of (meta)material with controlled elastic properties [PDF]

open access: yes, 2017
One of the most interesting challenges in the modern theory of materials consists in the determination of those microstructures which produce, at the macro-level, a class of metamaterials whose elastic range is many orders of magnitude wider than the one

Structural optimized mechanical metamaterial for multi transient high-g impact suppression and self-monitoring

open access: yesMaterials & Design
For extreme high-g mechanical impact of vehicle personnel and penetrating munition fuze, specific protections in terms of simultaneous high energy absorption performance, high recoverability and real-time alarming are urgent demands.

Electromagnetic wave absorption and structural properties of wide-band absorber made of graphene-printed glass-fibre composite [PDF]

open access: yes, 2018
Lightweight composites combining electromagnetic wave absorption and excellent mechanical properties are required in spacecraft and aircraft. A one- dimensional metamaterial absorber consisting of a stack of glass fibre/epoxy layers and graphene ...

Modulating light with light via giant nano-opto-mechanical nonlinearity of plasmonic metamaterial

open access: yes, 2015
From the demonstration of saturable absorption by Vavilow and Levshin in 1926, and with invention of the laser, unavailability of strongly nonlinear materials was a key obstacle for developing optical signal processing, in particular in transparent ...

Orthotropic metamaterials with freely tailorable elastic constants

open access: yesAIP Advances, 2023
To control mechanical waves and structural vibrations, an important method is to design metamaterials with tailored elastic constants, but it is very difficult. In this paper, a simple and universal metamaterial design method is proposed.

Multi-step self-guided pathways for shape-changing metamaterials [PDF]

open access: yes, 2018
Multi-step pathways, constituted of a sequence of reconfigurations, are central to a wide variety of natural and man-made systems. Such pathways autonomously execute in self-guided processes such as protein folding and self-assembly, but require external
