The UK Metamaterials Network brings together experts from academia, industry, and governmental agencies to resolve interdisciplinary challenges for this exciting field of emerging materials from theory, fabrication, experiment, to large-scale manufacturing and field testing. It is a joint endeavour between the EPSRC UK Metamaterials Network (EP/V002198/1; led by Prof Alastair Hibbins and Dr Anja Roeding from the University of Exeter) and the KTN Commercialising Metamaterials Innovation Network (led by Dr Steve Morris and Dr Robert Quarshie from the Knowledge Transfer Network).
