| Popis: | International audience; In this paper, an experimental methodology is presented in order to extract the dynamic properties of localized modes of a complex membrane. By applying the localization landscape theory, the resonant frequencies and regions of the localized modes can be obtained experimentally. This is implemented by a quasi-static measurement of the membrane deformation, and is performed without the knowledge of its tension field or any hypothesis about its homogeneity (uniform or non-uniform). The results are compared with Finite Element simulations and modal measurements made in vacuum conditions. |
