T. Y. Ha, G. H. Yoon. Finite Elements in Analysis and Design 235 (2024): 104138. This study examines the phenomenon of intrinsic nature in wave mitigation, specifically focusing on the concept of destructive interference (DI). When waves interact, they can exhibit either destructive interference or constructive interference depending on the phase difference. In the case of mechani...

R. Zheng, B. Yi, X. Peng, G. H. Yoon. Applied Sciences 14.2 (2024): 657. This paper presents an efficient and compact Matlab code for 2D and 3D topology optimization of multi-materials. We extend a classical 88-line-based educational code to the multi-material problem using the mapping-based interpolation function, with which each material is modeled equally and can obta...
