This will tell you exactly how to control the different medium properties.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/simulating-curved-transducer-field-patterns-in-a-layered-medium-air-and-water#post-6446 Sat, 05 May 2018 08:27:56 +0000 huanglin 6446@http://www.k-wave.org/forum/ <p>Hi Bradley,</p> <p> I want to simulate the Field Pattern in a layered medium. In my model the curved transducer is positioned in air, while I am trying to set the focal point in the water. I find the example_ewp_layered_medium.m and example_tvsp_transducer_field_patterns.m maybe helpful, but how can I define the velocity, density and attenuation coefficent of both the layers simultaneously？<br /> Meanwhile, I have no ideal how to consider the reflection effect between the two layers.<br /> In my opinion, the field pattern has no relationship with attenuation, so I can assume the two layers have the same attenuation coefficient, please let me know if this is possible?</p> <p>Best,</p> <p>Lin </p>
