Abstract The superior capability of wavefront manipulation makes metasurfaces a promising platform for implementing high‐density information storage and multifold optical encryption. Although some have realized encryption, it is still challenging to implement polarization‐encrypted grayscale images in both linear nonlinear channels. Here, novel approach realize multichannel encryptions proposed based on Malus composed single‐sized meta‐atoms, which the polarization states signals can be...
Abstract Metasurfaces have shown unprecedented capabilities and flexibilities for optical wave manipulation, which provide a powerful platform the integration minimization of multifunctional devices. However, realization multidimensional manipulation harmonic waves generated by nonlinear metasurfaces is still challenge due to lack theoretical guidance. Here, an efficient design strategy based on hydrodynamic model free electron dynamics demonstrated realize full complex‐amplitude modulation...
The Erlian basin is one of the most important basins in northern China to host sandstone-type uranium deposits (SUDs), which Bayanwula, Saihangaobi, and Hadatu are under development, name a few. Issues such as metallogenic mechanism mineralization these need be addressed throughout mining process. Over past several decades, 2D 3D seismic reflection surveys have been carried out study typical SUDs. technique has become effective geophysical tool (U) exploration, it used develop our...

Picking PP and PS sections for registration is required PP-PS joint inversion of PreSTM gathers. Because the characteristic PS-wave propagation associated with lower velocity frequency content, weaker reflectivity possible polarity reversal, manual picking based on data similarities not reliable enough to derive an accurate background Vp/Vs model. To avoid this problem, anisotropic PreSDM employed that takes advantage non-linear slope tomography. This provides depth-consistent imaging,...

Based on the parameter switching algorithm and discrete chaotic system, a new system based is proposed. The principles of are presented in detail by means flow chart step description. By applying phase diagram observation method, attractor approximation unified investigated algorithm. It shows that chaos can be obtained two periodic parameters state observed parameters. Thus formulas chaos+ = period+ period proved to workable this paper. Chaotic Rössler also studied employing methods. Two...
In this paper, a new non-linear inversion method was proposed to solve the AVO problems of PP and PS data. The is based on least square support vector machine (LSSVM). first step, angle gathers were obtained with help Zoeppritz equations then partially stacked after normal moveout (NMO) correction. second LSSVM model established in order define relationship between seismic reflection amplitude elastic parameters. Finally, parameters calculated according model. Then tested real results show...
