An engineering approach towards creating ubiquitous THz applications

Summary form only given. Within the wider terahertz (THz) frequency range (ca. 0.1 to 10 THz), the sub-millimetre wave frequency band (between 0.3 and 3 THz) is still considered to be a largely unexplored part of the electromagnetic spectrum. This `THz Gap', between conventional electronics and photonics, offers the real potential for both scientific and commercial exploitation. However, while the majority of THz groups focus on the former, it is the latter that offers the key to bridge the THz Gap to ubiquitous applications. To this end, new engineering solutions are needed in modelling (mathematical & numerical), design (synthesis & analysis) and fabrications (precision & volume production). As ubiquitous THz applications emerge, the costs of associated passive components, active devices and metrology will fall, creating a positive spiral of growth in all areas; enhancing our modern day living and with the prospect of a huge societal and economic impact.
