A broadband dual-mode monopole antenna using NRI-TL metamaterial loading
(2009)A printed monopole antenna is proposed which uses negative-refractive-index transmission-line (NRI-TL) metamaterial loading in order to achieve a broadband dual-mode operation. The metamaterial-loaded monopole supports a ...

A compact tri-band monopole antenna with single-cell metamaterial loading
(2010)A compact tri-band planar monopole antenna is proposed that employs reactive loading and a defected ground-plane structure. The reactive loading of the monopole is inspired by transmission-line based metamaterials (TL-MTM), ...

Compact, wideband and multiband antennas based on metamaterial concepts
(2010)In this review article, various antenna designs that are based on metamaterial concepts are presented which have been developed at the University of Toronto. Specifically, several antennas that are based on the zero-index ...

Few-electron systems in a quantum dot in a magnetic field: The Wigner molecule and paired electron phases
(2006)We have developed a variational many-body description for few-electron systems in a parabolic quantum dot in an external magnetic field. The ground state energy of the electronic system has been theoretically investigated ...

A folded-monopole model for electrically small NRI-TL metamaterial antennas
(2008)An improved model for analyzing electrically small NRI-TL antennas is proposed, that highlights the methods that enable these antennas to offer a good impedance match and a high radiation efficiency compared to previously ...

An investigation of printed Franklin antennas at X-band using artificial (metamaterial) phase-shifting lines
(2008)Non-radiating artificial phase-shifting lines are constructed using conventional positive-refractive-index (PRI) transmission lines (TL) and the recently developed negative-refractive-index (NRI) transmission lines. The ...

Magnetic and structural properties of stoichiometric thin Fe 3Si/GaAs(0 0 1) films
(2005)In this study, we report experimental results on the structural and magnetic properties of epitaxial Fe3Si films grown on GaAs(0 0 1) by co-evaporation. X-ray reflectivity shows that relatively smooth interfaces are obtained ...
