Abstract
An acoustic matching layer where the thickness is defined by a single layer of defined mono-disperse particles. The layer comprises a polymer base in which mono-disperse particles are embedded. The mono-disperse particles can be coated with a solid material that participates in the definition of the acoustic impedance of the layer. The polymer base can include smaller solid particles that participates in the definition of the acoustic impedance of the layer. The invention also provides a method of manufacturing.
