In 2011, the number of hungry people in the world surpassed one billion for the first time. The majority of these people are largely dependent for their food security upon resource-poor smallholder farmers in developing or emerging economies. These s

In this work we discuss the development of a multidimensional terahertz (THz) spectrometer, incorporating a range of THz generation and detection schemes in order to improve the flexibility and practicality of these complex experimental setups.

We investigate the effect of the effective substrate refractive index on the sensitivity of terahertz (THz) metamaterials for dielectric sensing by substrate etching. We found the effective refractive index near the metamaterials can be actively cont

We present broadband nonlinear THz spectroscopy and saturation of hydrogen-like electronic states of Arsenic ions, trapped in a solid Geranium substrate. The broadband pulses are generated by a photoconductive array.

We report on the design, fabrication and characterisation of large-area photoconductive THz array structures, consisting of a thin LT-GaAs active region transferred to an insulating substrate using a wafer-scale bonding process. The electrically insu

We demonstrate a significant enhancement in the sensitivity of split ring resonator terahertz metamaterial dielectric sensors by the introduction of etched trenches into their inductive-capacitive gap area, both through finite element simulations and

We report on the development of a large-area photoconductive THz array structure with an LT-GaAs active region fabricated on quartz substrates using a BCB bonding process. These are shown to generate high THz-fields greater than 100kV/cm, with a band
