Hi Brad,
Heterogeneous velocity and density maps are great features that add to the flexibility of K-Wave. Is there any chance you can add absorption to the list? The configuration that we would like to simulate involves significant path lengths through breast tissue and water. Now I have to choose either breast or water (low) absorption for the entire volume, which doesn't represent the system as well as I would like.
Thanks,
Dan

Hi Dan,
We agree that it is something that would be useful, but at the moment the absorption is included in the wavenumber domain (because it prevents us having to store the field at previous time-steps and so is efficient) which necessarily implies a homogeneous absorption value everywhere. If you can think of a good way around it without losing the efficiency please let us know!
Thanks,
