Hi,
I'm a new k-Wave user interested in simulating ultrasound propagation through a layered medium that includes both fluid and elastic materials. The layers, in order of wave propagation, are:
water → solid → soft tissue → solid → thin water layer → air
I’m considering using the pstdElastic3D model for this simulation, and I’d like to know:
Can pstdElastic3D handle a mixture of elastic and fluid media?
Especially, can it accurately model the interface between water and air, given the large impedance mismatch and strong reflections at that boundary?
Thanks so much for your help!
