This session addresses the analysis of Electromagnetic simulations and multiphysics interactions, drawing extensive interest from diverse research communities. It not only focuses on algorithms for electromagnetic simulations, but also includes co-simulation of various multiphysics phenomena, including mutual coupling in EM-circuit, EM-thermal, EM-plasma, electrical-acoustic, thermal-acoustic, and more, with a focus on circuit, device and system and SAW, BAW, FBAR devices in modern wireless communication.
