Elena Mavrona Publishes Paper!

Congratulations to Elena Mavrona, who has just published her first paper. Entitled Refractive indices and birefringence of hybrid liquid crystal – nanoparticles composite materials in the terahertz region it was published today in AIP Advances. The paper looks at introducing BaTiO3 nanoparticles to a liquid-crystal (LC) solution to create a hybrid LC-ferroelectric nanoparticle suspension. The …

Algorithm and Forum launched

Two new pages have been added to the website. The first page links to a parameter extraction algorithm written by the group, designed to output the complex refractive index of a material. The algorithm is free to use and requires a THz time-domain reference scan, a THz time-domain scan of the sample and the sample …

Paul publishes new paper in Electronics Letters

Paul Gow has published his second paper as lead author. The paper entitled “Characterisation of THz emission from double-metal-patterned gallium–arsenide multiple emitters” was published in Electronics Letters in mid-December, 2014.  The paper describes the effect on the emitted THz when using different metals for fabricating the double-metal emitters previously mentioned in Duncan’s paper.  It also describes the …

Lewis Maple publishes first paper

Lewis Maple has published hi first paper as lead author. The paper entitled “A metamolecule antenna for coplanar waveguides” was published in the journal Optics Express in December, 2014. The paper reports on a metamolecule antenna, based on a fish-scale design, that is augmented with two split-ring resonators (SRRs) placed within the fish-scale loops. The …

Paul and Duncan present THz research at Camogli, Italy

PhD students Paul Gow and Duncan McBryde presented their research at a Terahertz (THz) conference in Italy. Paul presented his work on multiplexing THz photo-Dember emitters by using a cylindrical lens array to a large audience. Duncan presented his poster on the characterising photo-Dember emitters on semi-insulting Gallium Arsenide (SI-GaAs) and low-temperature grown Gallium Arsenide …
