Excitation processes in the positive column of electrical discharges in inert gases
Published 1987“…Measurements of emission line profiles have been made using a pressure scanned Fabry-Perot interfermometer. High resolution absorption measurements have been made to give data on tha population densities of the lower excited states, and their variation with pressure and current, to assist in interpreting the intensity-current (I-i) results.…”

Planar antennas with enhanced bandwidth and radiation characteristics
Published 2017“…In this chapter, novel wideband and ultra-wideband (UWB) antennas that are based on loading the background plane of a monopole radiator with concentric split-ring resonators are presented. It is shown that this modification improves the fractional bandwidth of the antenna from 41 to 87%; in particular, the operational bandwidth of the proposed antennas is double that of a conventional monopole antenna of the same size.…”
