Founded in 2023 as a spinout from the United Kingdom Atomic Energy Authority (UKAEA), MuWave is building commercial high-power microwave sources—specifically next-generation gyrotrons—used to heat fusion plasma and enable applications such as satellite communications, radar, geothermal drilling and medical imaging. The company leverages patents and proof-of-concept prototypes originally created for the UK’s STEP Fusion power-plant programme. With its in-house engineering team and access to UKAEA expertise, MuWave plans to design, manufacture and export high-power microwave products from the UK while also offering consultancy services to fusion and non-fusion customers. The firm’s roadmap includes scaling production to meet anticipated demand from commercial fusion projects worldwide and expanding into adjacent deep-tech markets. Initial capital has been secured to accelerate product development and commercialisation. No operating metrics such as revenue or customer counts were disclosed in the article.
