Fig. 4: Effective polarizabilities of the Willis meta-layer.
From: An active mechanical Willis meta-layer with asymmetric polarizabilities
a Numerically retrieved amplitudes of the 16 normalized polarizabilities using the wave fields calculated in Fig. 3e at 10 kHz. Source data are provided as a Source Data file. b Numerically simulated wave fields at 10 kHz using the effective model characterized by the polarizabilities in Fig. 4a. (c, d) Numerically retrieved (c) amplitudes and (d) phase angles of normalized nonzero polarizabilities using the wave fields calculated in Fig. 3e. Source data are provided as a Source Data file.
