Bldg. ESPRIT, SAPHIR

This presentation begins with an overview of topology optimization based on stochastic and deterministic methods. We then focus on stochastic topology optimization based on Gaussian basis functions, which has been applied to the design of permanent magnet motors, dielectric lens antennas, and wireless power transmission devices. We extend this method to perform hybrid parameter-topology optimization, multi-material optimization, and fast optimization based on deep learning. Finally, we discuss the difficulties in stochastic topology optimization and its prospects.
