Genetic algorithm enables precise design of phononic crystals

Researchers at the University of Tokyo have utilized a genetic algorithm to design phononic crystals with precise vibrational properties. This algorithm automates the inverse design process, optimizing structures to control acoustic wave propagation in nanophononic materials. The approach was tested with light scattering experiments on a two-dimensional phononic “metacrystal,” demonstrating directional control of vibrations. This technology promises advancements in quantum computing, smartphones, and other communication devices by enabling custom-designed materials with enhanced acoustic properties.
