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…

Wave Manipulations by Coherent Perfect Channeling
Xiaonan Zhang, Chong Meng, Z. Yang
We report experimental and theoretical investigations of coherent perfect channeling (CPC), a process that two incoming coherent waves in waveguides are completely channeled into o…
