Characteristic mode theory is usually formulated on top of the electric field integral equation. We present in this paper a combined field integral equation based characteristic mode theory which is immune to the internal resonance corruption when the characteristic modes of closed perfectly conducting surfaces are iteratively solved for. Numerical results are presented to validate the proposed formulation...
The anisotropic hot-deformed (HDed) Nd-Fe-B magnets have attracted much attention for their remarkable magnetic properties and various applications due to the ultrafine grained microstructure. Hot deformation process usually consists of two subprocesses, hot pressing and die-upsetting. During this process, the initially isotropic nanocrystals in melt spun flakes transform to laterally elongated platelet-shaped...
Recently, high coercivity Nd-Fe-B permanent magnet has become an indispensable material for the traction motor of hybrid electric vehicles (HEVs) or electric vehicles (EVs) [1]. The microstructure control such as grain size and grain boundary is well known method for the high coercivity in HRE-free Nd-Fe-B magnets. Hydrogenation-disproportionation-desorption-recombination (HDDR) and melt-spinning...
We experimentally demonstrate the magnetic mirror behavior of all-dielectric metasurfaces at optical frequencies through phase measurements using time-domain-spectroscopy. The unique boundary conditions of magnetic mirrors can lead to advances in sensors, photodetectors and light sources.
