recommendations! Published in 2025 at "Scientific Reports"

DOI: 10.1038/s41598-025-91643-3

Abstract: Electromagnetic (EM) simulation is widespread in microwave engineering. EM tools ensure evaluation reliability but incur significant expenses. These can be mitigated by employing surrogate modeling methods, especially to expedite design workflows like local/global optimization or… read more here.
