One way to make a tilted half space would be:</p> <pre><code>% draw line line = makeLine(50, 50, [20, 1], [40, 50]); % find where line starts in each column [line_start, ~] = find(line); % fill it in for ind = 1:50 line(line_start(ind):end, ind) = 1; end % plot figure; imagesc(line);</code></pre> <p>Note, there are almost certainly more efficient ways to do this.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/medium-properties#post-7788 Thu, 03 Sep 2020 13:07:05 +0000 viku361 7788@http://www.k-wave.org/forum/ <p>hi brad,<br /> I want to form an interface which will be formed by two different mediums. And that interface can be tilted. How will i form the interface?

Open this in the MATLAB help browser to run and edit the code.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/medium-properties#post-7730 Sun, 09 Aug 2020 08:48:14 +0000 viku361 7730@http://www.k-wave.org/forum/ <p>hi everybody,<br /> I want to perform a simulation in which i have two mediums of different acoustic impedances.<br /> I want to see the beam profile when a sound wave from a single (large) round ultrasound transducer will emit and recieve the beam. What will be the beam behaviour at the interface of the two media.(in case of refraction i mean) </p>
