Surrogate-Assisted Electromagnetic-Focused Multiphysics Modeling and Optimization: An Overview

The importance of multiphysics analysis in the design of high-performance RF/microwave components and systems cannot be overstated. Grasping the interplay between various physical domains is crucial for a precise system analysis. In this paper, we present a comprehensive overview of the recent breakthroughs in multiphysics parametric modeling through the utilization of space mapping and in multiphysics optimization through the application of a pole-residue-based transfer function surrogate model. To demonstrate these cutting-edge methods, two examples of microwave components are provided.
