Greenerwave Secures €15m in Funding for Sustainable Innovation

Greenerwave, a spin-off from Institut Langevin specializing in electromagnetic wave control technologies, has successfully raised €15 million in fundraising. The funds were provided by the French Defence Innovation Fund managed by Bpifrance, Safran, Intelsat, BNP Paribas Développement, and Plastic Omnium.

Greenerwave has developed a groundbreaking technology that utilizes reconfigurable intelligent surfaces (RIS) and advanced algorithms to enhance the efficiency of signal-carrying waves in real-time. This innovative approach is not only more effective but also consumes less energy and requires fewer integrated circuits (ICs) compared to traditional antennas.

This significant fundraising achievement will enable Greenerwave to expedite the development of their transformative technology, which has the potential to revolutionize various sectors both in France and internationally. These sectors include defense, space, automotive, and telecommunications.

At the core of Greenerwave's technology are metasurfaces that consist of elements capable of shaping electromagnetic waves, allowing for the generation and control of directional beams. These metasurfaces are composed of pixels, which are centimeter-sized elements acting as micromirrors. Each pixel has the ability to modify the sign of the reflected wave.

By utilizing algorithms derived from the field of physics, Greenerwave effectively manages the interactions between pixels and microwaves, directing waves after they reflect on the surface. This passive, low-cost, and easily manufacturable technology aims to optimize the use of electromagnetic waves while significantly reducing energy consumption and production costs associated with antennas.

The application of Greenerwave's technology is expected to greatly enhance the transmission and quality of wireless signals in three major areas: telecommunications, both terrestrial and non-terrestrial connectivity (satellites), radar imagery, and the Internet of Things (IoT).
