Welcome to the Millimetre Wave and EPR Group in the School of Physics and Astronomy at the University of St Andrews. We are leaders in quasi-optical, mm-wave instrumentation, electron paramagnetic resonance (EPR) and undertake research in a broad range of areas. Whilst there is a good deal of overlap between research topics, our site is divided largely into material devoted to mm-waves and EPR. Please use the links below to view their respective pages.
