The 17th International Workshop on Optimization and Inverse Problems in Electromagnetism 2023 will be held on September 17-20, 2023, in Graz and is organized by IGTE.

The aim of OIPE 2023 is to discuss and share recent developments in optimization and inverse methodologies and their applications to the design and working principle of electromagnetic devices. A special focus will be put on machine learning techniques and optimal energy management. Please find the call for papers and the detailed list of scientific topics on the OIPE 2023 Website.

Additionally, after the workshop, a one-day doctoral course is scheduled. International experts will teach PhD students and researchers entering the field in selected aspects.

We are looking forward to meeting you in Graz in autumn 2023!
