Lire la suite >Metamaterials can be engineered for noise and vibration control due to their ability to manipulate waves in band gaps and due to local resonance effects. Metamaterials are often characterised in terms of effective parameters derived from an equivalent homogeneous medium. This work compares two inverse approaches to derive the frequency-dependent effective properties of symmetric metamaterial designs, including a multilayered medium and a periodic array of resonant inclusions in a host rubber medium. The effective properties corresponding to the effective complex wavenumber and the effective impedance obtained using the two inverse methods are identical for the 1D multilayered medium but exhibit slight variations for the 2D locally resonant medium.Lire moins >
