Abstract Terahertz (THz) waves show great potential in nondestructive testing, biodetection and cancer imaging. Despite recent progress THz wave near-field probes/apertures enabling raster scanning of an object’s surface, efficient, nonscanning, noninvasive, deep subdiffraction imaging technique remains challenging. Here, we demonstrate microscopy using a reconfigurable spintronic emitter array (STEA) based on the computational ghost principle. By illuminating object with STEA followed by...
Abstract Yttrium iron garnet, a material possessing ultralow magnetic damping and extraordinarily long magnon diffusion length, is the most widely studied insulator in spintronics magnonics. Field-free electrical control of perpendicular yttrium garnet magnetization with considerable efficiency highly desired for excellent device performance.

Abstract Plasticizers with amide groups (urea and formamide) polyols (glycerol, glucose, sorbitol) were used to prepare thermoplastic starch (TPS) containing NaCl salt as solid polymer electrolytes (SPE). Fourier Transform infrared (FT‐IR) spectroscopy revealed that both plasticizers Na + could form the interaction starch, had stronger hydrogen bond‐forming abilities than polyols. These interactions prevented molecules from crystallizing again, indicated by X‐ray diffraction (XRD). Scanning...

Utilizing spin pumping, we present a comparative study of the spin-charge conversion in RuO_{2}(101) and RuO_{2}(110) films. shows robust in-plane crystal-axis dependence, whereas exhibits an isotropic but stronger one. Symmetry-based analysis first-principles calculations reveal that originates from inverse Hall effect (ISHE) due to nodal lines splitting. In RuO_{2}(101), ISHE also dominates although splitting (ISSE) may coexist. These findings, sharp contrast previously attributed ISSE,...

A toroidal Alfvén eigenmode (TAE) excited by barely trapped energetic electrons during the application of a static magnetic perturbations (MPs) is observed for first time in tokamak ohmic heating plasmas. This TAE appears when current n = 2 MPs exceeds threshold value, at which forced reconnection happens. Here, mode number. located near plasma edge, agrees with calculation gap. It propagates ion diamagnetic direction and has dominant number 2. The frequency consistent precessional energy...
A numerical model for neoclassical transport under nonaxisymmetric magnetic perturbations in low collisionality plasmas tokamaks is developed.
