I found the backscattered wave of the k-space and the FDTD did not match when I using a cylinder inclusion with a homogeneous background.</p> <p>Do I have to smooth the object?</p> <p>Thanks. </p> http://www.k-wave.org/forum/topic/what-happens-when-acoustic-wave-passing-through-a-heterogeneous-media#post-3959 Mon, 14 Oct 2013 14:45:49 +0000 Bradley Treeby 3959@http://www.k-wave.org/forum/ <p>Hi bmezhou,</p> <p>Are you using k-Wave or your own k-space code? Could you tell us a little more about your simulation and what you expect to see?</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/what-happens-when-acoustic-wave-passing-through-a-heterogeneous-media#post-3953 Fri, 11 Oct 2013 14:28:02 +0000 bmezhou 3953@http://www.k-wave.org/forum/ <p>Or use this link <a href="http://instagram.com/p/fVCVw7ulHR/" rel="nofollow">http://instagram.com/p/fVCVw7ulHR/</a> </p> http://www.k-wave.org/forum/topic/what-happens-when-acoustic-wave-passing-through-a-heterogeneous-media#post-3951 Fri, 11 Oct 2013 13:53:07 +0000 bmezhou 3951@http://www.k-wave.org/forum/ <p>I'm performing some numerical study of acoustic propagation using a k-space method. When a acoustic pulse pass through a round inclusion, the acoustic field would become very complicated in the inclusion (see attached figure), which is not observed in the FDTD results.</p> <p><a href="http://pan.baidu.com/s/1GGlkD" rel="nofollow">http://pan.baidu.com/s/1GGlkD</a> </p>
