Inspired by electromagnetic waveguide cloaks with gradient index metamaterials, we fabricated a broadband cloak simply depth profile on the bottom and without any other structures top to confine water waves in certain area for cloaking regions. The new physics of mode conversion is first found. experimental numerical simulation results are good agreement show that presented device has nice performance various situations feasible over working frequencies. Being easy construct, this design...
The metasurface is widely used in wave manipulation because it has an excellent capability of phase modulation a simple way. In this work, we propose elastic that can achieve retroreflection flexural on thin metal plate. composed only two subunits with simplified design. By carefully selecting the thickness and material subunits, re-modulated, achieved at different incident angles. Furthermore, single-phase two-component fixed constraints free boundaries, respectively, are studied. results...
By assembling the square lattice arrays of “+” shaped steel rods, an underwater acoustic composite lens consisting a convex and slab is proposed to achieve convergence waves. In order study focusing ability, numerical simulations experiments in silencing pool are carried out among range frequencies between 15 kHz 25 kHz. As result, 3-D wave inspiringly achieved observed. Particularly, vertically extended from 2-D lens, but it found be able focus waves three-dimensional manner. Comparisons...
The out-of-plane metal-insulator-graphene (MIG) heterostructure separated from metal substrates by a silica spacer has been intensively investigated. Both numerical simulations and theoretical calculations exhibit that due to the dominating effect of adjacent layers, multiple strongly confined Fabry-Pérot (F-P) resonances are simultaneously excited on ingenious MIG heterostructure; thus, conductive realization nine-band plasmonic perfect absorber at mid-infrared wavelengths. spectral...
The differential quadrature method has been developed to calculate the elastic band gaps from Bragg reflection mechanism in periodic structures efficiently and accurately. However, there have no reports that this successfully used of locally resonant structures. This is because, process using structures, non-linear term frequency exists matrix equation, which makes it impossible solve dispersion relationship by conventional matrix-partitioning method. Hence, an accurate efficient numerical...
A semianalytical method for the transient response of functionally graded material (FGM) rectangular plates under various boundary conditions, by use state space method, differential quadrature and numerical inversion Laplace transform, is proposed in this study. The FGM plate simply supported at two opposite edges with any classical conditions on other edges, such as supported, clamped, free conditions. Comparisons show results generated present agree well those predicted finite element...

One of the common approaches to compensate for grayscale performance limitation in time-multiplexing light field displays is employ a halftone technique. We propose an ordered-dithering algorithm based on 3-dimension super-mask increase gray levels display. Our method makes full use overlapping perceived pixels which are caused by design, such that effectively trading-off spatial resolution and color performance. A real-time rendering display prototype built validate proposed algorithm....
This paper proposes a novel method to create wide-angle and high-resolution videos from video sequences by assembling the individual overlapping frames. As we know, register frame of different on same plane using perspective matrix synthesize overlapped region nonlinear blending which is time-consuming task; moreover, scene depth frequently varying for dynamic content. Therefore, projection transform should be changed as content in real time. To tackle these problems, propose robust...

Since then several conferences symposiums held...
Abstract A Lagrangian radial basis function‐based particle hydrodynamics method (RBFPH) is proposed. In RBFPH method, the differential quadrature technique combined with function (RBF) to obtain meshless high‐dimensional derivative approximations for randomly distributed particles; a particular solution of RBF chosen ensure positive definite interpolating matrix. Like conventional RBF, has advantages simple form, isotropy and high accuracy, suitable numerical calculation. Moreover, all...
