sponsible for undesired behavior in radiation field patterns and electroacoustic response of the ultrasound transducers for medical imaging. This undesired behavior is ultimately impairing the end echographic image quality [1,2]. The aim of our research is to study the influence of the dicing depth, for given kerf material properties, on the cross-coupling dB level. Mechanical cross-coupling was analyzed in the case of a 1-D ultrasound transducer using finite element modeling (FEM). The results were compared with experiments that were based on impedance analysis, laser interferometry and hydrophone measurements.
