Acoustic Wave Amplitude Control Using Interference Phenomenon in Hybrid Geometric-Phase Meta-atom Pairs
This paper presents a novel method for continuous acoustic wave amplitude modulation by leveraging the interference phenomenon between two mode-conversion paths in a hybrid geometric-phase meta-atom (HGPM) pair, achieving nearly 100% modulation depth by simply adjusting the relative orientation angle of the meta-atoms.
Reconstruction of Reverberation Theory in Diffuse Sound Fields Using Reflection Order Analysis
The author proposes a new mathematical model for reverberation in diffuse sound fields that accounts for the temporal energy distribution in each reflection order. The model is consistent with the author's previously proposed revised reverberation theory and demonstrates the importance of the concept of "reverberation of direct sound" for the entire reverberation process.
