Multiphysics Modeling of Phase Change Materials with Laser Pulses

At the 16th Pacific Rim Conference on Ceramic and Glass Technology & GOMD 2025 in Vancouver, NewFoS postdoc Wataru Takeda shared advances from Project #2: Topological Acoustic Wave RF Devices.

His study uses finite element analysis to explore how micron-thick films of phase-change materials—GST225 and Sb₂S₃—respond to nanosecond laser pulses at 1064 nm. These findings are paving the way for more efficient, low-loss RF devices.

💡 This research showcases how multiphysics modeling and materials science can unlock the next generation of RF innovation.
