A compact microstrip crossover using NRI-TL metamaterial lines
Abbasi, Muhammad Ali Babar; Antoniades, Marco A.; Nikolaou, Symeon (2018)A practical implementation of a miniaturized crossover is presented using negative-refractive-index transmission-line (NRI-TL) metamaterial lines. NRI-TL metamaterial theory has demonstrated that by loading a conventional ...

On the Use of Tunable Power Splitter for Simultaneous Wireless Information and Power Transfer Receivers
Quddious, Abdul; Abbasi, Muhammad Ali Babar; Tariq, Muhammad Haroon; Antoniades, Marco A.; Vryonides, Photos; Nikolaou, Symeon (2018)The use of a tunable power splitter (PS) as a constituent component of a simultaneous wireless information and power transfer (SWIPT) system is discussed. Two varactor diodes are used to achieve a tunable output power ratio ...
