<jats:p>The present paper describes a simplified procedure for determining the Poisson’s ratio of homogeneous and isotropic viscoelastic materials. To that end, a cylindrical shaped material is axially excited by an electromagnetic shaker and displacement waves are investigated. Using a frequency sweep as an excitation signal, the frequency domain displacement response is measured upstream and sideways of the sample itself and, by using a plane cross section analytical model of the experimental setup, the Poisson’s ratio is estimated using a minimization based procedure applied on radial displacement once the complex modulus has been directly determined under the assumption of spring-like behavior of the axial displacement. The results are presented and discussed for different materials and compared with well-established quasi-static and finite element simulations.</jats:p>
