Localized modes prediction in a membrane with non-uniform tension from the quasi-static measurement of its localization landscape

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