Wave Control Through Active Metamaterials
The goal of this project was to create a bistable deployable metamaterial that, when deployed, can redirect or attenuate waves in a body of water. The unit cells were designed to hold 200 grams of weight in each stable state, be quickly and consistently deployed, and, as a full material, work to attenuate waves at a wide range of frequencies. The project began with the unit cell design which used origami metamaterials as the main bistable structure as well as a motor and propeller to produce the force required for deployment, as well as incorporate spinning structures into the design which can be used to manipulate wave control based on factors such as angular velocity. The unit cells were tested for deployment and bistability and were adjusted to improve the efficiency of the system. Once created, the unit cells were duplicated and arranged in the x and y direction to test for wave propagation and attenuation both while the material was stationary, and spinning. This was modeled numerically and experimentally which allowed for comparison of the resulting dispersion and FRF plots to observe bandgaps in the frequencies being tested.
