- Abstract
The article focuses on the development of devices related to wave sculpting. It says that the principles and technology involves in wave sculpting includes symmetry breaking, light waves shaping, and wave-scatter controlling. It features the sonic crystal reported by X-F. Li and colleagues which offers unidirectional sound transmission through sawtooth spatial asymmetry. It adds that the device is easy to handle and modifies the transmitted frequency sound.
