This episode of the Physics World Weekly podcast explores the science and commercial applications of metamaterials with Claire Dancer of the University of Warwick and Alastair Hibbins of the University of Exeter.

They lead the UK Metamaterials Network, which brings together people in academia, industry and governmental agencies to support and expand metamaterial R&D; nurture talent and skills; promote the adoption of metamaterials in the wider economy; and much more.

According to the network, “A metamaterial is a 3D structure with a response or function due to the collective effect of meta-atom elements that is not possible to achieve conventionally with any individual constituent material”.

In a wide-ranging conversation with Physics World’s Matin Durrani, Hibbins and Dancer talk about exciting commercial applications of metamaterials including soundproof materials and lenses for mobile phones – and how they look forward to welcoming the thousandth member of the network sometime in 2025.
