Ferrite isolators are attractive due to their excellent isolation, low loss, good linearity, and high-power performance. However, these devices usually operate over a single-frequency band. Multiband applications are possible if the isolation bandwid

The Thevenin and Norton equivalent models of a receiving antenna cannot be used to calculate the antenna's scattered power because they are too simplistic. Based on the reciprocity theorem, a more elaborate equivalent model, consisting of a passive d

Alien crosstalk (AXT) between Ethernet cables produces interference and poses a potential threat to system security. AXT is challenging to measure in pre-existing installations because of the need for instrumentation at both the near- and far ends. A

The optimal radar detection of miniature unmanned aerial vehicles (UAVs) requires that the radar cross-section (RCS) of the UAVs be known. Although RCS estimates may be obtained from computer simulation and conventional static RCS measurements, the r
