Nature Materials, 2014 Balancing the complexity and the simplicity has played an important role in the development of many fields in science and engineering. As Albert Einstein was once quoted to say: 'Everything must be made as simple as possible, but not one bit simpler'. The simplicity of an idea brings versatility of that idea into a broader domain, while its complexity ...

Reports on Progress in Physics, 2023 Abstract Mechanical metamaterials, also known as architected materials, are rationally designed composites, aiming at elastic behaviors and effective mechanical properties beyond (‘meta’) those of their individual ingredients—qualitatively and/or quantitatively.

Nanotechnology Reviews, 2013 Plasmonics and metamaterials have attracted considerable attention over the past decade, owing to the revolutionary impacts that they bring to both the fundamental physics and practical applications in multiple disciplines. Although the two fields initially advanced along their individual trajectories in parallel, they started to interfere with each ...

CoSP: Reconfigurable Metamaterial Inverse Design via Contrastive Pretrained Large Language Model. [PDF]
Adv Sci (Weinh)In this work, CoSP (contrastive multi‐state pretrain), an intelligent inverse design method for reconfigurable metamaterials based on a contrastive pretrained large language model, is proposed. Numerical experiments demonstrate that CoSP can design reconfigurable metamaterial structures for multi‐state, multi‐band optical responses, showing great ...

Science, 2009 Tunable Metamaterials The electromagnetic response of metamaterials gives rise to exciting phenomena such as cloaking, negative refraction, and perfect lensing. Their response, however, tends to depend strongly on resonant effects, thereby limiting the application bandwidth. Driscoll et al.

Experiments on Nonlocal Fluid-Flow Metamaterials. [PDF]
Adv Sci (Weinh)A nonlocal fluid‐flow metamaterial composed of standard microfluidic tubes and connectors is designed. Hence, the current of the system at one position depends on the gradient of fluid flow at many other positions, leading to unusual alternating backward and forward laminar flows of water.

Beyond-Classical Ferroelectric Metamaterials: 3D-Printed Planar Lattices With Programmable Electro-Thermo-Mechanical Coupling. [PDF]
Adv Sci (Weinh)Planar ferroelectric lattices with rationally‐tailored topology and polarization achieve programmable piezoelectric and pyroelectric properties. Analytical modeling, homogenization, and experiments collectively demonstrate enhanced and tunable longitudinal, transverse, and shear piezoelectric responses, together with substantially improved ...

Optics Letters, 2022 We study the dispersion of electromagnetic waves in a spatially dispersive metamaterial with Lorentz-like dependence of principal permittivity tensor components on the respective components of the wave vector performing the analysis of isofrequency contours. The considered permittivity tensor describes a triple non-connected wire medium.

Journal of Optics, 2010 Optical space in metamaterials may be engineered to mimic the landscape of a multidimensional Universe which has regions of different topology and different effective dimensionality. The "metamaterial landscape" may include regions in which one or two spatial dimensions are compactified.

Metamaterials and imaging [PDF]
Nano Convergence, 2015 Resolution of the conventional lens is limited to half the wavelength of the light source by diffraction. In the conventional optical system, evanescent waves, which carry sub-diffraction spatial information, has exponentially decaying amplitude and therefore cannot reach to the image plane.
