Perfect Seismic Wave Absorbers for the 8th Magnitude Earthquakes
Liang Sun, Feilong Xu, Zhen Liang +2
Most modern buildings and infrastructures are not designed to resist 8th magnitude earthquakes, for which studies on phononic crystals and local resonators reported so far are not…

Acoustic Pressure Monopole, Velocity Monopole, and Hybrid Monopole
Suet To Tang, Xiaonan Zhang, Chong Meng +1
We show that there are two types of acoustic monopoles, namely the pressure monopoles (PMs) and the velocity monopoles (VMs). Under one wave incidence, only the pressure field near…

Tunable Extremely Asymmetric Acoustic Metasurfaces Made by Coupled Membrane Resonators
Songwen Xiao, Suet Tao Tang, Z. Yang
We report the experimental demonstration of tunable asymmetric acoustic metasurfaces with extreme contrast, made by two decorated membrane resonators (DMRs) coupled via a sealed ai…
