In the ultrasonic car parking sensor example from the following link: https://www.comsol.com/model/ultrasonic-car-parking-sensor-68041, I have created a ray acoustic model for the scenario. However, I am only able to detect direct ray paths and I would like to consider retroreflection, where the sound goes to the road, reflects, and then goes to the object before returning to the detector. In my case, the obstacle is very small, such as a curbstone, and I want to assess the impact of retroreflection, particularly at a specific distance where it becomes stronger. Can you please explain what kind of changes are required in the wall domain, or if there are any other options in Comsol to consider retroreflection?
