Many emerging technologies will have an impact on the grid and on other key elements of our electrical systems, electrical operations and the broader infrastructure. One of the most important types of ...

Metalenses have emerged as a new optical element or system in recent years, showing superior performance and abundant applications. However, the phase distribution of a metalens has not been measured ...

Metalens is a kind of optical metasurface composed of metaatoms for manipulating incoming light's amplitude, phase, and polarization. Unlike traditional refractive lenses, metalens can modulate the ...

In this paper, the hybrid combination of genetic algorithm and particle swarm optimization (GAPSO) is used to optimize the phase distribution (PD) of beam-scanning reflectarray. The GAPSO takes ...

Overcurrent protection is a common practice for the detection of faults on the distribution system, including downed wire. It is an appropriate and industry accepted methodology for system protection; ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...
