Over the past two decades, terahertz time-domain spectroscopy1 and quantum-cascade lasers2 have been two of the most important developments in terahertz science and technology. These technologies may contribute to a multitude of terahertz applications that are currently under investigation globally3. However, the devices and components necessary to effectively manipulate terahertz radiation req...
Metamaterials exhibit numerous novel effects and operate over a large portion of the electromagnetic spectrum. Metamaterial devices based on these effects include gradientindex lenses, modulators for terahertz radiation and compact waveguides. The resonant nature of metamaterials results in frequency dispersion and narrow bandwidth operation where the centre frequency is fixed by the geometry a...
