In this paper, guided modes in isotropic chiral nihility metamaterial fibers coated with graphene layers supported by conventional dielectric material are studied theoretically. Kubo formalism is applied to model the conductivity of single-layer graphene, and suitable boundary conditions at proposed waveguide structure. The dispersion equation for fiber normalized cut-off frequency derived. Characteristic curves forward backward modes, effect layer, influence chirality parameter, energy flow...
This paper proposes a simple, low-profile rectangular microstrip patch antenna for 5G applications in the 37-40 GHz band.The initial design involved basic antenna, which was modified to operate efficiently target frequency antenna's performance improved by adjusting S11 and VSWR through an inset feed improve matching between feeding line radiating element.Further improvements were made inserting two slits, leading resonating at 37.9 39.68 expanding impedance bandwidth.The designed using...
We demonstrated the theoretical analysis of characteristics a surface Plasmon metallic circular waveguide with core region filled magnetized plasma material. The dispersion relations are derived using Maxwell's equation and suitable boundary conditions. cutoff frequency Surface Polariton (SPP) wave at metal-magnetized interface have been obtained computationally. influence radius cylinder, cyclotron frequency, on effective mode index, propagation length analyzed. observed that existence...
Abstract In this paper, a facile and efficient preparation strategy for porous hydrophilic chitosan sponge is demonstrated, combining surfactant pore-foaming agent. The resulting possesses an interconnected pore structure soft texture, exhibits fast water absorption rate capacity, the compressed can achieve full shape recovery 5 s after absorbing water. Moreover, our process removes residual acid commonly found in sponges prepared by method. addition, results demonstrate useful...
Guardrail end terminals and roadside crash cushions are common technologies deployed to absorb redirect the energy of a colliding vehicle. The purpose these devices is reduce damage structures vehicles while limiting effects collisions have on motorists. primary mode absorption through physical deformation. This deformation can often create hazardous scenarios for vehicle occupants. paper shows study new (patent pending) attenuator composed multi-chambered, fluid-filled barrier. Kinetic...
In direct laser deposition (DLD), metallic powder is injected into the melt pool in order to join different metals develop fully dense and near net shape part. The cost of wasted commercial DLD machines has been a major concern industries. More than 60% being disposed off which make system economically environmentally expensive. Recycling not feasible many sectors, because fear drop quality product. objective this study enhance efficiency process, so that minimize amount wasted. present...
Abstract The research conducted here aims to expand the operating load range and offset manufacturing costs of tapered-land hydrodynamic bearings by creating deflecting bearing sectors through use selective laser sintering. motivation this study comes from fact that required taper depth thrust is determined before dependent on expected axial loads. If applied exceeds for which was selected for, will not operate efficiently, an increased rate wear occur. Here, are designed deflect during...
Abstract Thin-walled axial crushing members, or crush tubes, are often utilized as energy absorbers due to their high strength weight ratios. Applications of such devices include automotive, aerospace, and structural components. Core materials graded honeycomb other support members have shown greatly increase absorbing capacity, while improving stability during deformation collapse. The ideal performance through exhibits numerous stepwise collapse mechanisms, folding, up complete exhaustion...
A general analytical compliance model is presented for symmetric flexure hinges formed of serial segments known compliances and with thicknesses defined analytically. Serial combination, mirroring, translation individual yield the compliances. As an illustration, a right elliptical corner-filleted hinge are studied. For aluminum sample dimensions l = 0.0254 m, 0.006 b 0.008 t 0.0015 w 0.00635 experimental testing, finite element simulation, results very close. Results this study include...
