Hi, I am trying to use the k-Wave toolbox for my master's thesis on Underwater Acoustics. I am interested in simulating the wave propagation of acoustic waves, up to about 50 - 100 kHz in shallow waters. The bathymetry (seafloor) of shallow waters acts as a frequency-dependent absorber. I do not know how to model this condition in the k-Wave toolbox. I am not interested in modelling the wave propagation into the subsurface, I just want to apply some kind of absorption/impedance condition on a surface (with varying depth) in a 3D domain. Can somebody please help me on this? Could not find anything in the documentation or in this forum.
Thanks,
Karan
