Dr. Jonathan Gratus is a Senior Lecturer in the Department of Physics at Lancaster University. His research focuses on the mathematics of charged particle modeling and electromagnetic fields in particle accelerators, including conventional vacuum accelerators like CERN's LHC and laser-driven plasma wakefield accelerators. He investigates Coherent Synchrotron Radiation (CSR), beam-plasma interactions, ultra-relativistic approximations, the Maxwell-Vlasov equations, and the Klimontovich distribution. Additionally, he explores the stress-energy-momentum tensor of electromagnetic fields in media and has developed a pictorial introduction to differential geometry for students of general relativity.

Recent work includes computational modeling of engineered spatially dispersive materials (e.g., metamaterials) for applications in RF technologies and MIMO waveform optimization. His projects involve numerical simulations using HFSS, CST, and Comsol, with a focus on disorder effects in wire arrays and longitudinal EM wave propagation. Current grants include Cockcroft Institute core funding (2025-2028) and phase 4 projects (2021-2025).
