Spring-mass matching layers consisting of a thin polymer layer (massless spring) covered by a metal layer (incompressible mass) can be designed to achieve any desired acoustic impedance and act as an equivalent lambda/4 matching layer. In this paper, we present a fabrication process of these matching-layers based on spin-coated PDMS as spring layer and stainless steel commercial foils as mass layer.
