About awarded research

Hiroaki Deguchi, Kei Matsushima, Takayuki Yamada, Realization of viscoelastic modulus bounds via numerical investigation and topology optimization based on homogenization of 6mm hexagonal lattice, JASCOME Symposium 2025, Japan Society for Computational Methods in Engineering, 19-20th December 2025, Himeji, 15-251219.
Recently, significant attention has been drawn to non-Hermitian physical phenomena, which do not occur in energy-conserving Hermitian systems but emerge exclusively under specific parameters in non-conservative systems. In this study, we developed an structural optimization method to realize desired complex moduli using viscoelastic composite materials, and numerically verified the theoretical bounds of these complex moduli. This enables the systematic design of devices utilizing non-Hermitian physical phenomena, which emerge only under specific parameters, by employing viscoelastic materials.

Your impression & future plan

I have always been fascinated by the theories behind structural forms, which has motivated my research. I am truly honored that my work has been recognized in this way. At the same time, I would like to express my sincere gratitude to everyone who has supported me. Moving forward, I would like to continue to work on designing structures through theoretical and numerical approaches.
