Mathieu Mivelle, ERC PoC 2026 : MAGMA – Extreme Microwave Field Enhancement at the Nanoscale Award Winner

For over a century, electromagnetic waves in the MHz to GHz range have revolutionised technology; yet their generation remains limited by macroscopic dimensions. This constraint hampers innovation, as modern systems require precise control of the electromagnetic field at the nanometre scale – a domain largely inaccessible to conventional sources.

To address this challenge, this project proposes an innovative technology designed to enable intense and localised manipulation of the electromagnetic field. By fabricating structures with nanometre-scale precision, this approach enables unprecedented field confinement, achieving amplification factors in excess of ten million.

The aim of this proof of concept is to validate these exceptional properties using diamond-based quantum microscopy. Ultimately, this technological platform will open up major opportunities in cutting-edge sectors, ranging from quantum architectures to high-performance data storage and microelectronics.
