讲座摘要：

        Acoustic wave propagation: numerical modeling and its control via acoustic metamaterial/metasurface。This talk will be divided into two parts. In the first part, I will talk about our recent work on numerical modeling of acoustic wave propagation (at ultrasound frequency range) in heterogeneous media. Specifically, a mixed-domain method was developed that is capable of modeling linear or nonlinear wave propagation in arbitrarily heterogeneous media in a computationally efficient manner. I will talk about its potential applications in biomedical ultrasoundand other areas. In the second part, I will talk about our recent work on acoustic metamaterials and metasurfaces. This part will include our work on acoustic hyperbolic metamaterials, acoustic complementary metamaterials, and acoustic metasurfaces for asymmetrical sound transmission.
