Nanostructured optical coatings with tailored spectral absorption properties are of interest for a wide range applications such as spectroscopy, emissivity control, and solar energy harvesting. Optical metamaterial absorbers have been demonstrated variety customized single band, multiple polarization, angular configurations. However, metamaterials that provide near unity absorptivity super-octave bandwidth over specified wavelength not yet experimentally. Here, we show broadband,...
Quasi two-dimensional metasurfaces composed of subwavelength nanoresonator arrays can dramatically alter the properties light in an ultra-thin planar geometry, enabling new optical functions such as anomalous reflection and refraction, polarization filtering wavefront modulation. However, previous metasurface-based nanostructures suffer from low efficiency, narrow bandwidth and/or limited field-of-view due to their operation near plasmonic resonance. Here we demonstrate for high-efficiency,...
Three-dimensional (3D) printing is a modern, computer-aided, design-based technology that allows the layer-by-layer deposition of 3D structures. Bioprinting, technology, has attracted increasing attention because its capacity to produce scaffolds for living cells with extreme precision. Along rapid development bioprinting innovation bio-inks, which recognized as most challenging aspect this demonstrated tremendous promise tissue engineering and regenerative medicine. Cellulose abundant...
Metamaterials have the potential to create optical devices with new and diverse functionalities based on novel wave phenomena. Most practical systems require that device properties be tightly controlled over a broad wavelength range. However, metamaterials are inherently dispersive, which limits operational bandwidths leads high absorption losses. Here, we show deep-subwavelength inclusions can controllably tailor dispersive of an established metamaterial structure thereby producing...
Based on coordinate transformation incorporated with conformal mapping approach, a sub-wavelength imaging device magnification, called "planar hyperlens" is designed, capable of realizing far-field plane-to-plane beyond the diffraction limit. The possible implementation method proposed by using effective anisotropic metamaterial formed alternating metallic and dielectric thin layers. magnification performance designed multi-layer lensing structure numerically simulated to confirm our...
We designed an electromagnetic refractor and a phase transformer using form-invariant coordinate transformation of Maxwell's equations. The propagation direction energy in these devices can be modulated as desired. Unlike the conventional dielectric refractor, fields at our refraction boundary do not conform to Snell's law isotropic materials impedance this is matched which makes reflection extremely low; wave front from cylindrical plane realized with slab structure. Two dimensional...
A circular cylindrical and an oblate perfect lens are designed by using coordinate transformation theory. Theoretical analyses performed to give insight into the variant angular magnification in lens. We further take advantage of system make object surface flat for future practical imaging lithography applications. also first time systematical simulations various kinds lens, including numerical confirmation Mankei Tsang's statement about planar magnifying performance beyond diffraction limit...
Omni-directional electromagnetic field concentrators have been recently reported by Marco Rahm et al. [Photon. Nanostruct.: Fundam. Appl. 6, 87 (2008)] based on form-invariant coordinate transformations related to its Jacobi transformation matrix. Using transverse-electric wave illumination, we reduced the complex material parameters of concentrator for future practical implementation. Concentrators with different set permittivity and permeability tensors are proposed. The concentrating...
The stability and mechanical thermodynamic properties of Al11RE3 intermetallics (RE = Sc, Y lanthanide La-Lu) have been investigated by combining first-principles Debye model calculations. It was found that the formation enthalpies are all negative, indicating they stable; moreover, experimental values Al11La3 Al11Ce3 in good agreement with predicted values, which −0.40 kJ/mol −0.38 kJ/mol, respectively. calculated results reveal Young’s modulus E shear G La, Ce, Pr, Nd Sm) obviously greater...

Digital twins are propelling the next generation of industrial revolution and serve as a key technology in enabling intelligent water conservancy. However, due to diversity objects within conservancy scenarios complexity related factors, research application digital field remain immature. There still significant challenges constructing fine‐grained, high‐fidelity twin for their corresponding scenarios. In this context, taking polder areas subjects, area system is proposed, which includes...
