A matching layer is formed as a composite, such as a 2-2 or a 1-3 composite. The base material forms some portion, such as 5 or more percentage by volume, of the composite matching layer and volume. The in-fill, bonding or acoustically isolating material holds the sections of base material together and provides for control of the stiffness and cross coupling. By using an electrically conductive base material, electrical conductivity is provided from a top surface to a bottom surface. The composite is easily manufactured using dicing of a base material, filling of the kerfs and curing the filled kerfs.
