This paper presents simulation and experimental results of a metallic wire-pair structure (H-pair) negative-index materials (NIM) and examine the dielectric characteristics of this structure in the THz frequency range using THz time-domain spectroscopy (TDS). This structure possesses negative index features at normal incidence. This makes measurements, that are otherwise difficult to carry out, possible...
Due to the increasing extension of power grids and decentralization of power generation, the need for control and compensation is more and more increasing. The intensive use of modern power electronics in FACTS elements can provide a feasible solution. Especially STATCOM and UPFC, for their versatile application can be the method of choice. Voltage sourced converters with IGBTs are used for compensation,...
