In this work, effects of long-term high temperature services on surface micro-structures and components of SmCo magnets with Ni coating were studied. The magnets have been serviced at 550 °C in air (0∼5000 h). And the laws of the surface degradation were studied. And the characters of surface micro-structures and composition were observed by SEM, EDS, and XRD.
An effective technique combining high-frequency (HF) asymptotic methods with the integral equation method via a novel current-based hybrid scheme is proposed for the analysis of antenna-platform problems. The proposed technique employs a relatively large full-wave region for accurate modeling of antenna current distribution. The full-wave region is then divided into two parts, with one of them including...
Fringe equivalent currents expressions derived by Michaeli are finite for all aspects of illumination and observation except for the Ufimtsev singularity. However, they may yield inaccurate results when the direction of the incident ray is near the edge under consideration. Alternative expressions of fringe equivalent currents are derived in this communication to overcome the drawback. They are obtained...
