If so, use this value as the <code>radius</code> input to <code>makeBowl</code>.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/focused-transducer#post-6704 Tue, 08 Jan 2019 06:02:34 +0000 peiliu 6704@http://www.k-wave.org/forum/ <p>Hello,<br /> I'm trying design a 3D PTF transducer with a radius of 12 mm and the focal length of 50mm. I use the function of the makeBowl,but how can I define the focal zone like 40mm,trying to compare a ball source in the focal zone and out of the focal zone ? </p>
