Optical logic gates play important roles in all-optical circuits, which lie at the heart of next-generation optical computing technology. However, intrinsic contradiction between compactness and robustness hinders development this field. Here, we propose a simple design principle that can possess multiple-input-output states according to incident circular polarization direction based on metasurface doublet, enables controlled-NOT infrared region. Therefore, directional asymmetric...
In this paper, a dual-band perfect metamaterial absorber based on graphene is proposed in the terahertz region. The consists of two sizes disks and gold film separated by dielectric spacer unit cell. numerical results demonstrate that absorption can be achieved superposition specific peaks induced different disks. resonance frequency tuned via controlling conductivity achieve selectively tunability it tune each independently. And will not changed when small move along diagonal within range...
Abstract Silicon oxycarbide (SiOC) possesses great potential in lithium‐ion batteries owing to its tunable chemical component, high reversible capacity, and small volume expansion. However, commercial application is restricted due poor electrical conductivity. Herein, rambutan‐like vertical graphene coated hollow porous SiOC (Hp‐SiOC@VG) spherical particles with an average diameter of 302 nm are fabricated via a hydrothermal treatment combined CH 4 pyrolysis strategy for the first time....
We demonstrate that multi-band coherent perfect absorption can be achieved at infrared frequencies by a metasurface in which four-sized columnar metal patches are separated dielectric layer unit cell. The bandwidth is enhanced three times compared with single-band while high absorbance maintained. polarization-independent and independently modulated each resonant frequency tuning the phase difference of two incident beams. Moreover, sensitive to radius patch, thus wide range obtained...
The Na4Fe3(PO4)2(P2O7) (NFPP) cathode material for sodium-ion batteries (SIBs) is modified through a facile yttrium (Y)-doping approach. crystal structures, surface morphologies, and electrochemical performances of the pristine Y-doped samples are comparatively investigated. results indicate that structure morphology almost unchanged after Y doping. Doping with an appropriate amount can enhance electronic conductivity kinetics material, leading to superior performance. Among four prepared...

Abstract As the 2D counterpart of metamaterials, metasurfaces have drawn wide attentions in recent years due to their unique electromagnetic (EM) properties and subwavelength footprints. Although great efforts been made metasurface‐based full vectorial manipulation EM waves, realization multifunctional devices with high compactness is still challenging. Here, by employing mutual coupling between meta‐atoms induce spin‐selective magnetic resonance, a generalized design principle based on...
Compared with conventional mirrors that behave as isotropic electromagnetic (EM) reflectors, metamirrors composed of periodically aligned artificial meta-atoms exhibit increased degrees freedom for EM manipulations. However, the functionality most is fixed by design, and how to achieve active control still elusive. Here, we propose a multistate metamirror based on nonvolatile phase change material Ge2Sb2Te5 (GST) four distinct functionalities can be realized in infrared region exploiting...
Magnetic solitons in spinor Bose-Einstein condensates confined a one-dimensional optical lattice are studied by the Holstein-Primakoff transformation method. It is shown that due to long-range light-induced and static magnetic dipole-dipole interactions, there exist different types of solitary excitations parameter regions. Compared conventional solid-state materials, parameters this type an can be easily tuned above which highly controllable experiments.
The dynamics of Bose-Einstein condensates in optical lattices with the long-range dipole-dipole interactions, short-range on-site and hopping terms is reduced to generalized discrete nonlinear Schr\"odinger equation. We present different types solitary excitations which appear parameter regions. anticipate that these will be observable discuss how model parameters can tuned experiments.
