The Kelvin-Voigt model is used to model the loss, which gives an power law dependence of 2 for small attenuation. </p> http://www.k-wave.org/forum/topic/viscoelastic-simulation-on-kwave#post-9113 Tue, 16 Jul 2024 16:33:14 +0000 masud407 9113@http://www.k-wave.org/forum/ <p>Hello,</p> <p>If I want to simulate the viscoelastic medium, I just need to define α0 ≡ medium.alpha_coeff and y ≡ medium.alpha_power which ranges from 0 to 3. Is there any specific things I should do?</p> <p>Thanks </p>
