Publications

The success of the COTS programme has been a direct result of collaborative activity between all four partners. This has not only already led to publications in well-cited journals and conference presentations, but has also delivered the ground work for demonstrating the next generation of technologies to open up the THz spectrum for widespread scientific and commercial exploitation
