Scalable Metagrating for Efficient Ultrasonic Focusing
Yan Kei Chiang, Li Quan, Yugui Peng +4
Acoustic focusing plays a pivotal role in a wide variety of applications ranging from medical science to nondestructive testing. Previous works have shown that acoustic metagrating…
Acoustic meta-atom with maximum Willis coupling
Anton Melnikov, Li Quan, Sebastian Oberst +3
Acoustic metamaterials are structures with exotic acoustic properties, having promising applications in acoustic beam steering, focusing, impedance matching, absorption and isolati…
Non-Reciprocal Willis Coupling in Zero-Index Moving Media
Li Quan, Dimitrios L. Sounas, Andrea Alu
Mechanical motion can break the symmetry in which sound travels in a medium, but significant non-reciprocity is typically achieved only for very large motion speeds. Here we combin…
Maximum Willis Coupling in Acoustic Scatterers
Li Quan, Younes Ra'di, Dimitrios Sounas +1
Willis coupling in acoustic materials defines the cross-coupling between strain and velocity, analogous to bianisotropic phenomena in electromagnetics. While these effects have bee…
