Dr. Jonathan Breeze

Biography

Jonathan Breeze studied Astrophysics at Leeds University and worked at the National Physical Laboratory (NPL) in the Quantum Metrology division as a Scientific Officer. He later joined Matra-Marconi Space and British Aerospace Space Systems (now Airbus Space & Defence), where he served as a Microwave Design Engineer on multiple satellite programs. Breeze was responsible for developing passive microwave systems for spacecraft payloads, conducting research on advanced microwave components utilizing high temperature superconductors (HTS) and specialized ceramic dielectrics. He returned to academia to focus on fundamental research involving microwave dielectric ceramics, culminating in his PhD which explored the theory and experiments on microwave absorption in single-crystal metal oxides. He developed a microwave photonic crystal cavity that achieved a record Q-factor of 600,000 at 30 GHz at room temperature, leading to research on room-temperature solid-state masers, with significant results achieved in optically-excited single-crystal systems. Notably, his research has led to demonstrations of both pulsed and continuously-operating room-temperature masers utilizing nitrogen-vacancy defects in diamond. Breeze was awarded the Royal Society University Research Fellowship in 2019, receiving the Henry Moseley Medal from the Institute of Physics, and in 2023 he was awarded the Michael Faraday Medal and elected a Fellow of the Institute of Physics.
