An anisotropic magnetic metamaterial combined with an elastic medium. wo layers of the bulk sample are shown. a, The metamaterial before the electromagnetic field is applied. b, The metamaterial is compressed by the electromagnetic forces acting between the elements. Dimensionless lattice parameters a and bare normalized to the resonator radius r₀.
