The tapered slot antenna, such as Vivaldi, has been widely used due to its ultra-wideband, high gain, simple feed structure, and easy fabrication. However, there is no rigorous analytical theory for this type of antenna. This paper analyzed the metal parts of a tapered slot antenna in a conical coor...

The unbalanced impedance of the asymmetric 3-phase wind power permanent magnet synchronous generator (PMSG) compensated by external circuits in series with the 3-phase windings is investigated in this paper. The asymmetric impedance includes the unbalanced resistances, unbalanced self-inductances, a...

Integrating the electric vehicle into grid or microgrid has been receiving more and more attention in recent years. Typically, the electric vehicle (EV) chargers with their power batteries have been developed for vehicle-to-home(V2H) applications, acting as a backup generation to supply emergency po...

We report a novel self-powered nanocomposite sensor composed of K_0.5Na_0.5NbO₃ (KNN) nanoparticles (NPs) and multiwalled carbon nanotubes (MW-CNTs). The KNN NPs and MW-CNTs are dispersed in polydimethylsioxane by mechanical agitation to produce a piezoelectric nanocom...

Rapidly decreasing prices for renewable energy, increasing industrialization and electrification of the global economy, and a world-wide focus on reducing carbon emissions, is causing a reexamination of the power system of the future. A reliance on centralized planning and control, scheduled and dis...
