Seminar #2: Stuart Barth – “A Uniplanar Metamaterial-Inspired Electromagnetic Bandgap Structure



This work introduces a novel, uniplanar, electromagnetic bandgap structure.  Using transmission-line metamaterial techniques, a shielded, conductor-backed coplanar waveguide is periodically loaded with series capacitors and shunt inductors to support a backwards-propagating (left-handed) mode. Using multiconductor transmission-line analysis, it is shown that contra-directional coupling creates one or more bandgaps, which can be modelled very accurately with a proposed equivalent circuit. Fully-printable structures are designed and fabricated, and are shown to effect suppression of parallel-plate modes in one and two dimensions over electrically short distances.


Stuart Barth received the B.Sc. and M.Sc. degrees in electrical engineering in 2012 and 2015, respectively, from the University of Alberta, Edmonton, AB, Canada, where he is currently working towards the Ph.D. degree in electrical and computer engineering. His current research interests include the study of multiconductor transmission-line RF/microwave circuits, dispersion engineering of periodic structures, fundamental electromagnetic theory, antenna radiation-pattern shaping, and the design of artificial materials for use in communications networks. Mr. Barth was awarded the IEEE AP-S Pre-Doctoral Research Award in 2014 for his ongoing research into electromagnetic bandgap structures for GPS antenna applications. He currently serves as the communications officer of the IEEE Northern Canada Section MTT-S/AP-S joint chapter.

Free pizza and refreshments will be served.
