Previously, scientists knew only one type of curved optical rays—Airy beams and their derivatives. They were obtained back in 2007. Due to their physical properties, the beams can be used for manipulating small particles, which can be applied in microfluidics and cell biology. Obtaining such beams requires advanced equipment. Therefore, researchers from all around the world are looking for new types of curved beams that could be obtained much easier.

"Principles of obtaining new curved beams are an interesting and promising research field for both fundamental and applied areas. In 2018, our team theoretically predicted the existence of a new type of curved hook-like self-accelerating light beam. We named it a photonic hook, which is a curved electromagnetic wave. After that, we wondered if such curved beams could be obtained from an acoustic wave? Our new study positively responded to this challenge. We can obtain this beam incomparably easier than Airy...
