We have developed a function-theoretic method to study near-field diffraction by multiple-edge. The methodology and our new series solution are useful in practical applications such as the Silent Aircraft Technology.
Material property is closely related to wave propagation in elastic solids. We are developing a new theory on Acoustic Black Hole as well as Aero-Acoustic MetaMaterials for efficient control of elastic/acoustic wave energy in materials.
Our research topics cover the wave phenomena at multiscale structures in order to understand the physics of wave scattering by heterogeneous micro-structures and propose an innovative design for new materials.
Another interesting topic in bio-acoustics is to identify the hidden mechanism of insects to use vibro-acoustic signal for food assessment. Development of bio-inspired technology based-on survival strategy of social insects is our ultimate goal.
