Novel Hybrid Simulation Of Large 128 By 128 Pixels Input To Ultrasonic Wavefront Computing Apparatus

Recently, the Ultrasonic wavefront computing apparatus (UWFCA) was introduced to compute the Fourier Transform (FT). Piezoelectric transducers are traditionally simulated by the Finite Element Method (FEM). However, FEM simulation of large transducer arrays and a large SiO

medium (4

) is computationally intractable on standalone workstations. Hence, we demonstrate, for the first time, a successful hybrid simulation of a GHz UWFCA that contains a large 128×128 bulk-acoustic-wave (BAW) transducers array.
