Abstract
In an ultrasound transducer arrangement having an electroacoustic transducer part, at least one acoustic matching layer is allocated to the transducer part. The acoustic matching layer is composed of an electrically conductive skeleton having interspaces connected to one another. The skeleton is constructed of particles connected to one another. The size of the particles is smaller than the wavelength of an acoustic wave in a matching layer, as a result of which no significant scattering of the wave occurs in the matching layer. The interspaces are filled with a curable casting compound.
