For a 1D simulation use <code>kspaceFirstOrder1D</code> and set <code>medium.sound_speed</code> and <code>medium.density</code> to have the three regions. Here's a 1D example to get started <a href="http://www.k-wave.org/documentation/example_ivp_1D_simulation.php">Simulations In One Dimension Example</a>. This example is an initial value problem, and you may want to define a time-varying source instead. With large impedance changes, as there will be between PZT and water, it's important to ensure convergence with a convergence test (ie. keep halving the grid spacing until the output doesn't change).</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/simulating-singular-transducer-with-matching-layer#post-8458 Thu, 17 Feb 2022 19:55:41 +0000 snaik 8458@http://www.k-wave.org/forum/ <p>Hello Dr. Treeby, First of all, thank you for creating an excellent toolbox. I am a novice. I would like to set up a simulation of a singular transducer (not an array) with matching layer and transducer impinging wave into soft tissue. It's a simple setup: Transducer-&gt;Matching Layer-&gt;Soft tissue. Which examples can I look at to accomplish this? How do define the layer stack? FYI: I would like the students to explore acoustic impedance mismatch (e.g. having no matching layer vs matching layer, moderating the acoustic impedance values of the matching layer, etc.). Thank you again for your help. </p>
