Researchers Create Type II Vortices In Laboratory Water
Scientists generated new vortex types using subwavelength holes to simulate natural tidal wave interactions.
Updated on Oct. 21, 2026 in Physics
Researchers have successfully generated type II vortices in a laboratory water wave system using a dipole-oscillating subwavelength hole. This experimental setup allows scientists to concentrate wave energy and orbital angular momentum on a scale smaller than the waves themselves.
Why it matters
Understanding how these vortices concentrate energy is critical for studying wave patterns found around natural obstacles like islands. The mechanism provides a model for two-dimensional wave systems that could be applied across various geophysical scales.
The system achieves 2πℓ phase accumulation for generated vortices within a controlled environment. These results provide insight into real-world tidal scenarios like those seen near New Zealand, Madagascar, and Iceland, where natural tidal wavelengths reach 10,000 km.
The details
The team created the vortices by inducing interference between a dipole-oscillating subwavelength island and an incident plane wave in a system with no intrinsic chirality. By adjusting the relative phase and amplitude of these two wave components, researchers were able to precisely control the properties of the resulting vortices.

The Big Picture
This discovery shifts the understanding of wave mechanics by demonstrating that type II vortices can form around holes in a plane without traditional phase singularities. It bridges the gap between small-scale laboratory experiments and the complex physics of large-scale oceanic tidal-wave vortices found near islands like New Zealand, Madagascar, and Iceland.
This research provides a fundamental breakthrough in wave control that could eventually inform more efficient maritime engineering and coastal protection technologies. By mastering the concentration of wave energy at subwavelength scales, engineers may develop better tools for managing wave impact in harbor environments.
The takeaway
This experiment proves that complex vortex behavior can be replicated and controlled through simple interference patterns in a laboratory setting. Readers interested in fluid physics can observe similar, naturally occurring vortices by examining tidal patterns around isolated islands.
