“…In recent years, the inertial amplification was demonstrated in the axis twist metamaterials as well [56,57]. Subsequently, an analogue of Thomson scattering was proposed theoretically, numerically, and experimentally to describe its underlying physics [58]. From the physics point of view, the coupling of orthogonal polarizations is a means to amplify the inertia [56,57,59], while the destructive interference is another key factor in opening the bandgap [58].…”
