Mode Conversion in Acoustic Module (Snell's Law)

Please login with a confirmed email address before reporting spam

Hi,

I want to implement Snell's Law in COMSOL (in the Acoustic Pressure Transient Module) to take into account the Mode Conversion by reflection (and refraction) at the boundaries. A quick overview of the theory of this Mode Conversion can be seen in the link below and in the attached *png.

Maybe it is phenomena already implemented in the Acoustic Modele. But till now I have not found it yet.
Right now I am using Sound Hard Boundary (Wall) for this specific boundary. This is stating that the pressure 'flux' is zero through this boundary. Do I have to use weak constraint (or something) to implement the Mode Conversion phenomena?
