Abstract Additive manufacturing (AM) creates digitally designed parts by successive addition of material. However, owing to intrinsic thermal cycling, metallic produced AM almost inevitably suffer from spatially dependent heterogeneities in phases and mechanical properties, which may cause unpredictable service failures. Here, we demonstrate a synergistic alloy design approach overcome this issue titanium alloys manufactured laser powder bed fusion. The key our is in-situ alloying Ti−6Al−4V...
Abstract Additive manufacturing (AM), known as 3D printing, enables rapid fabrication of geometrically complex copper (Cu) components for electrical conduction and heat management applications. However, pure Cu or alloys produced by printing often suffer from either low strength conductivity at room elevated temperatures. Here, we demonstrate a design strategy high strength, uniformly dispersing minor portion lanthanum hexaboride (LaB 6 ) nanoparticles in through laser powder bed fusion...
We demonstrate theoretically that Fano resonance can induce a negative optical scattering force acting on plasmonic nanoparticles in the visible light spectrum when an appropriate manipulating laser beam is adopted. Under illumination of zeroth-order Bessel beam, nanoparticle at its exhibits much stronger forward than backward and consequently leads to net longitudinal force, termed resonance-induced force. The extinction spectra obtained based Mie theory show arises from interference...
To satisfy the property requirements for biodegradable medical implants, Zn alloyed with low levels of Mg (≤0.8 wt%) has attracted increased research interest. In present study, deformation twinning was observed in tensile tests and appears to have an adverse impact on ductility. The profuse as-cast Zn-Mg alloys accelerated crack growth tension due impingement which caused local stress concentrations initiates cracking. As-rolled better ductility than their counterparts inhibition by refined...
By employing the angular spectrum representation, we successfully derive partial-wave expansion coefficients of circular Airy beams (CABs) with different polarizations, based on which scattering a spherical particle in CABs is solved exactly. Special attention focused exploring potential applications abruptly autofocusing (AAF) property and optical manipulation microparticle by force. It found that both linear polarizations are best candidates to implement AAF robustly against strong...
We demonstrate a sharply asymmetric reflection in geometrically symmetric magnetic metamaterial (MM) system, which originates from the coupling of electromagnetic (EM) wave to surface plasmon resonance states and broken time reversal symmetry MM. Based on this effect, we have designed unidirectional EM waveguide, bender, beam splitter. Our simulations indicate that designs possess merits robustness against strong defect disorder, controllability with an external field, addition finite...
Based on the generalized Lorenz-Mie theory and Maxwell stress tensor formulism, we calculate transverse force constant matrix perform a linear stability analysis spherical particle that is subject to negative longitudinal optical (NLOF) under illumination of Bessel beams. Phase diagrams with respect material parameters are presented, which exhibit possibility appearance NLOF. From dynamical simulations performed both in plane along direction, an even clearer picture realization stable NLOF...
We demonstrate that a lateral optical force (LOF) can be induced on chiral nanoparticles immersed in the two interfering plane waves. The LOF push nanoparticle sideways, direction relying helicity of particle as well phase difference between Analytical theory reveals comes mostly from direct coupling vorticity with chirality. In particular, has magnitude comparable to gradient and radiation pressure when chirality is sufficiently large. may serve for sorting due its unusual properties also...
We demonstrated a construction of negative-index material (NIM) with ${\ensuremath{\epsilon}}_{\mathrm{eff}}={\ensuremath{\mu}}_{\mathrm{eff}}=\ensuremath{-}1$ employing ferrites only, no metallic components. Our design the NIM is motivated by recent coherent potential approximation results and corroborated exact numerical calculation demonstrating negative refraction an electromagnetic beam, equal incident angles, as well slab imaging phenomena, source-image separation twice thickness. The...
We demonstrate a dramatically molded reflection of an electromagnetic (EM) wave from the magnetic metamaterial (MM) surface occurring near plasmon (MSP) resonance. It is found that on one side source reflected field nearly cancels incoming field, giving rise to shadowy region MM surface, while other considerably enhances resulting in brightened region. Our analysis indicates this effect arises coupling EM MSP band states which exhibit giant circulations going only direction due broken time...
We demonstrate a magnetically controllable nonreciprocal Goos-H\"anchen (GH) shift enabled by the magnetic plasmonic gradient metasurfaces (GMSs) consisting of an array ferrite rods with rotation introduced to rod dimers in unit cell. The incident Gaussian beam is observed exhibit evident GH about $5\ensuremath{\lambda}$ when it from one side, whereas for geometrically symmetric direction respect surface normal only very small comes into appearance. phenomenon arises unidirectional coupling...
Lateral optical forces in a direction perpendicular to light propagation have attracted increasing interest recent years. Up now, all lateral can be attributed the symmetry breaking directions caused by either morphology of scatterer geometry or fields impinging on scatterer. Here we demonstrate, both numerically and analytically, that when an isotropic breaks electric-magnetic symmetry, new type anomalous force induced along translational invariance where illumination striking has no...
We examine the mechanism governing photonic band gaps (PBGs) in two-dimensional magnetic crystals consisting of ferrite cylinders, based on simulation structure and transmission spectra. Besides conventional PBG resulting from Bragg scattering, two other types PBGs, owing, respectively, to Mie scattering resonance spin-wave resonance, are identified. Of particular interest is due that can be regarded as a analog surface plasmon metal. The ``magnetic plasmon'' induced resonant PBGs shown...
