However, the phases of the transducers are software controllable. This gives us full control over the beam shape exiting the transducer array. ## Working principle -focussing the waves to an arbitrairy point in 2d space + +[](img/gifsmos_double_focus.gif) ## Setup There are two array's used in the levitation example. One is facing upwards and the other is facing downwards. They are facing eachother with a distance of 70mm. this distance is arbitrarily chosen based on the needed volume for levitation.
