Tunable performance of indium tin oxide-zinc oxide as Q-switcher by Zalkepali, N.U.H.H., Awang, N.A., Ghosh, B.K., Mohamad, K.A., Alias, A., Mahmud, N.N.H.E.N., Zamri, A.Z.M., Muhammad, N.A.M.

“…The mechanical exfoliation technique is applied to serve the ITO-ZnO as SA and inserted in a single-ring cavity design. The QPEDFL in a single ring cavity gives the repetition rate, pulse width, average output power, pulse energy, and SNR of 38.49 kHz, 5.50 µs, 0.47 mW, 12.72 nJ, and 64.20 dB, respectively. …”

Planar antennas with enhanced bandwidth and radiation characteristics by Alibakhshikenari, Mohammad, Naser-Moghadasi, Mohammad, Sadeghzadeh, Ramazan Ali, Virdee, Bal Singh, Limiti, Ernesto

“…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.…”
