However, if you want to model a cylindrical shaped initial pressure source, you could use a combination of <code>makeDisc</code> and <code>repmat</code>. For example,</p> <pre><code>cyl = repmat(makeDisc(32, 32, 16, 16, 5), [1, 1, 32]); voxelPlot(cyl);</code></pre> <p>Brad. </p> http://www.k-wave.org/forum/topic/cylindrical-source-in-3d-for-photoacoustic-spectroscopy#post-5968 Tue, 30 May 2017 07:02:01 +0000 Ansrcha 5968@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I have been trying to simulate acoustic field in PA cell. In order to get the simulations, I need to define source element as a cylindrical source(laser beam approximation) in 3D. Can you tell me how to define the source mask in order to get the laser beam as a cylindrical source. </p> <p>Thanks a lot. </p>
