Power loss and electromagnetic energy density in a dispersive metamaterial medium

open access: yes, 2009
The power loss and electromagnetic energy density of a metamaterial consisting of arrays of wires and split-ring resonators (SRRs) are investigated. We show that a field energy density formula can be derived consistently from both the electrodynamic (ED)

Impact of Ambient Temperature on Shunt Capacitor Placement in a Distorted Radial Distribution System

open access: yesEnergies, 2018
In electrical distribution systems, shunt capacitors are installed in order to reduce system losses, to enhance the voltage profile, and to free up system capacity. Nevertheless, the installation of shunt capacitors in distribution systems with distorted
