French SME designing metamaterial devices for MRI enhancement, vibration energy harvesting, and acoustic wave control across multiple engineering domains.
Multiwave Technologies is a Marseille-based SME specializing in metamaterial design and electromagnetic engineering, with deep expertise in manipulating wave behavior across multiple physical domains. Their core work involves developing metamaterial-based devices for medical imaging (particularly MRI enhancement through dielectric pads and custom head coils) and vibration energy harvesting. They bridge advanced wave physics — acoustic, elastic, and electromagnetic — with practical applications in healthcare, energy, and structural engineering, typically contributing specialized metamaterial design and radiofrequency engineering to research consortia.
MRI PADS (dielectric shimming), M-ONE (metamaterial head coil for ultra-high field MRI), BLOC (NMR for lab-on-chip), and SILENCE (acoustic noise cancellation for MRI) all target MRI/NMR improvement.
MetaVEH (both as participant and third party) focuses on metasurface-based resonator arrays for harvesting ambient vibrations and converting them to usable energy.
BOHEME (bio-inspired hierarchical metamaterials for seismic isolation and acoustics), SILENCE (acoustic noise cancellation), and EffectFact (wave propagation mathematics) all involve wave manipulation.
MRI PADS, M-ONE, and BLOC all require specialized RF coil and electromagnetic field engineering for MRI/NMR systems.
EffectFact applies Wiener-Hopf and Riemann-Hilbert factorization techniques to wave problems in biomechanics, geomechanics, and environmental engineering.
Multiwave's earliest H2020 involvement (2019-2020) centered on MRI-specific metamaterial applications — dielectric pads, NMR spectroscopy for microfluidics, and bio-inspired wave-control materials. From 2021 onward, their focus broadened significantly toward energy harvesting via metasurfaces and resonator arrays, acoustic noise control, and applied mathematical methods for wave problems. This shift suggests a deliberate expansion from a medical-imaging-focused metamaterial company toward a broader wave-physics platform applicable across energy, structural, and environmental domains.
Multiwave is evolving from an MRI-focused metamaterial specialist into a cross-domain wave engineering company, with energy harvesting and acoustic applications becoming their growth vector.
Multiwave has never coordinated an H2020 project — they consistently join as a specialist participant or third-party contributor, indicating they bring focused technical capability rather than project management. With 49 unique partners across 17 countries, they operate as a widely networked niche expert that different consortia bring in for metamaterial and RF engineering tasks. Their split between participant (4) and third-party (4) roles suggests they are frequently called upon for specific technical contributions without being a core consortium member.
Multiwave has collaborated with 49 distinct partners across 17 countries, a remarkably broad network for an SME of this size. Their Marseille base and FET/MSCA participation connect them primarily to European academic and research institutions working on advanced materials and wave physics.
Multiwave occupies a rare niche: they are one of very few European SMEs that can translate metamaterial theory into engineered devices across multiple wave domains — electromagnetic, acoustic, and elastic. Their dual strength in MRI hardware and energy harvesting metamaterials means they can contribute to consortia in both health technology and clean energy. For consortium builders, they offer the rare combination of deep physics expertise with the agility and applied focus of a small company.
