From: Enhanced flexural wave sensing by adaptive gradient-index metamaterials
Flexural wave dispersion relations and the related effective bending stiffness of the adaptive metamaterial.
Left: Flexural wave dispersion relations of the adaptive metamaterial with different uniformly distributed shunting circuits. Right: effective bending stiffness of the adaptive metamaterial when −cN/cpT = −0.98. Shaded areas denote the subwavelength and regular Bragg band gaps, respectively.
