Systems and methods for machine learning based active metasurfaces for flexural and/or longitudinal wave control and harmonics generation

A method of controlling waves, comprising:

• detecting, with a plurality of sensors attached to a plurality of beams, a fundamental incident wave in the plurality of beams;
• determining, based on signals from the plurality of sensors generated in response to the fundamental incident wave, a frequency of the fundamental incident wave;
• and
• controlling a plurality of actuators connected to the plurality of beams to generate at least one of a cancellation wave, a subharmonic wave, and a superharmonic wave, based on the frequency of the fundamental incident wave.

A non-transitory computer-readable medium for controlling waves, including instructions that, when executed by one or more processors, cause the one or more processors to:

• detect, with a plurality of sensors attached to a plurality of beams, a fundamental incident wave propagating in the plurality of beam;
• determine, based on signals from the plurality of sensors generated in response to the fundamental incident wave, a frequency of the fundamental incident wave;
• and
• control a plurality of actuators connected to the plurality of beams to generate at least one of a cancellation wave, a subharmonic wave, and a superharmonic wave, based on the frequency of the fundamental incident wave.
