Non-reciprocal sound propagation in space-time modulated media
Junfei Li, Chen Shen, Yangbo Xie +1
Realization of non-reciprocal devices, such as isolators and circulators, is of fundamental importance in microwave and photonic communication systems. This can be achieved by brea…

Perfect Generation of Angular Momentum with Cylindrical Bianisotropic Metasurfaces
Junfei Li, Ana Díaz-Rubio, Chen Shen +3
Recent advances in metasurfaces have shown the importance of controlling the bianisotropic response of the constituent meta-atoms for maximum efficiency wavefront transformation. U…

A Surface Impedance-Based Three-Channel Acoustic Metasurface Retroreflector
Chen Shen, Ana Díaz-Rubio, Junfei Li +1
We propose the design and measurement of an acoustic metasurface retroreflector that works at three discrete incident angles. An impedance model is developed such that for acoustic…
