Designs of electromagnetic (EM) coil have attracted a lot attention in the research community due to its applications several areas human endeavours. However, optimal selection wire size and current design Square Air-Core Multi-turn Multilayer Electromagnetic Coil (SAMMEC) with significant diameter for both safe cost-effective products has not been given enough attention. Therefore, equation fl...

Metamaterials with magnetic properties have been widely investigated with rather complex twoand threedimensional resonant structures. Here we propose conceptually and demonstrate experimentally a mechanism for broadband optical magnetism in simpler one-dimensional systems. We experimentally demonstrate that alternating high-index dielectric/metal multilayer hyperbolic metamaterials can exhibit ...

Magnetically driven miniature soft robots exhibit fast and dexterous responses to an applied external magnetic field. With remote manipulation, controlled navigation of can be realized within hard-to-access spaces for potential use in the human body. Existing using digital light processing are fabricated from planar sheets, thus have limited shape transformations locomotive behaviors. Herein, a...

We propose and analyze a decoupled time-marching scheme for the coupling of the Landau-Lifshitz-Gilbert equation with a quasilinear diffusion equation for the spin accumulation. This model describes the interplay of magnetization and electron spin accumulation in magnetic and nonmagnetic multilayer structures. Despite the strong nonlinearity of the overall PDE system, the proposed integrator re...
