   hi everybody,
   I want to perform a simulation in which i have two mediums of different acoustic impedances.
   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)

   Hi viku361,

   You could take a look at the Snell's Law And Critical Angle Reflection Example as a starting point. Open this in the MATLAB help browser to run and edit the code.

   hi brad,
   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? Please suggest me @ vivekraj361@gmail.com

   Hi viku361,

   The medium properties are just MATLAB matrices, so you can define them using any way you like. One way to make a tilted half space would be:

   % 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);

   Note, there are almost certainly more efficient ways to do this.

   Brad.

   Hello Sir, How can I create a spherical interface for two heterogeneous mediums?
