You can compute the intensity by setting <code>sensor.record = {&#39;I&#39;, &#39;I_avg&#39;}</code>. This will return the intensity in each Cartesian direction, which you can then assemble to give the intensity vector at each position.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/poynting-vector-direction-of-wave-propagation#post-3665 Tue, 21 May 2013 00:09:00 +0000 Kenton 3665@http://www.k-wave.org/forum/ <p>Hi there,</p> <p>First off - k-wave is great and is really simplifying my life! I just have one question that I can't seem to figure out - is there any way to extract the direction of wave propagation / the pointing vector from a simulation?</p> <p>I know you can easily extract particle velocity using sensor.record, but I'm looking for the localized direction of wave propagation.</p> <p>Thanks for any help you can offer! </p>
