Then, set the focus position of each element to be the (0, 0, 0) or the wherever the centre of the concave sphere is.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/problem-about-kwavearray#post-7590 Wed, 10 Jun 2020 02:23:15 +0000 jackYANG 7590@http://www.k-wave.org/forum/ <p>Hi Brad,</p> <p> I briefly tested the kwaveArray program, which is a great contribution,I know it's easy to get an off-grid source or sensor, but if I want an off-grid source with multiple arrays on a concave sphere, what should I pay attention to, and how are these arrays arranged in a concave sphere?And how to control the radius of curvature and aperture of concave sphere?Can you give me a quick example of a specific mask that we can use as a reference for our study? It seems that we haven't been successful so far.</p> <p> jackYANG </p>
