Hi Brad,
I am confused about power-law absorptions in the elastic simulation. You mention that your material properties in your papers [2], [3] (especially α0,model in compression=8.83 dB/(MHz^2cm), in shear=19.5 dB/(MHz^2cm)) for skull bone in your simulation based on this paper [1]. But compression=70 Np/m and shear=213 Np/m absorptions constants were used in the referenced paper [1]. How did you convert Np/m to dB/(MHz^2cm)? Also, I read your paper[2] however I couldn't find any function or method in k-Wave.
Thank you for your effort and attention!
Thank you,
Michael
