Non-linear wave mixing animation

For linear waves, different wave modes do not interact while similar wave modes can only interfere constructively or destructively. However, non-linear ultrasonic waves of different modes can interact with each other under specific conditions to produce a resonant wave. This is depicted in this small animation. Different wave modes are shown as different colours (blue and green). The resonant wave is shown in red.

Thanks to the University of Bristol and my supervisors (Bruce Drinkwater and Anthony Croxford) for supporting this work.

First to watch but don't even know what that means
