The current paper describes the application of modelling and numerical simulation of these phenomena in structures like complex microelectronic samples or acoustic lenses. The design of acoustic lenses and their active elements have been optimized based on the numerical studies performed here. Simulation based visualization of the wave propagation and energy conversion in a Through Silicon Via with different defects at 1 GHz acoustic frequency supported the understanding and interpretation of the received acoustic signals.enconference paper
