Efficient numerical frameworks for modelling ultrasonic beams propagating across interfaces
André Lello de Almeida, Melody Png, Bo Lan
Two different frameworks are developed to model the wave field generated by a transducer and propagating through one or more interfaces, and a Quasi-Monte Carlo (QMC) integration s…
