Abstract
A wave control system includes a substrate with a plurality of beams spaced apart from each other, a plurality of sensors disposed on the plurality of beams, a plurality of actuators disposed on the plurality of beams, a processor, and a memory communicably coupled to the processor. The memory stores machine-readable instructions that, when executed by the processor, cause the processor to determine a frequency of a fundamental incident wave propagating within and/or incident on the plurality of beams based on a plurality of signals from the plurality of sensors, and control the plurality of actuators 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. In addition, a reflected fundamental wave, the sub harmonic wave, and/or the superharmonic wave can be steered to a desired direction or path along the substrate.
