Hi all,
I am trying to build a simulation, that would simulate the propagation of an ultrasound wave (5-20 Mhz) through a multi-layered stackup(3-4 mediums), where thick of each medium is 1-5 mm, below is a basic diagram depicting the same. An object would be placed at the end of the stack, that would reflect back 90% of the incoming signal. I am doing this by adjusting the speed of sound at the end, such that reflection coefficient at the end is 0.9. The goal here is to measure the strength of the echo response obtained after the round-trip transmission. I wanted to know how I should go about coding this into K-wave. Any advice would be helpful.
Thanks in advance
