a The schematic of the scattering system. One unit cell is removed from the center of the metamaterial to create a dipole scatterer. A Gaussian beam is normally incident on the metamaterial. b The schematic of the scattering of transverse sound inside the metamaterial. The blue cube denotes the scatterer. c The amplitude of the transmitted pressure field. d The velocity amplitude in the micropolar effective medium due to the interference of \(s=-1\) scattered field with the background field. e The real part of the \(s=-1\) scattered velocity field in the micropolar effective medium.
