Metamaterials, famously likened to Harry Potter's invisible cloak, are artificial nano structures designed to manipulate light properties. However, the practical application of this technology in everyday life depends on the commercialization of the manufacturing process which requires significant costs.

A research team led by Professor Junsuk Rho from the Department of Mechanical Engineering and the Department of Chemical Engineering, researcher Won-Geun Kim and Ph.D. candidate Hongyoon Kim from the Department of Mechanical Engineering at Pohang University of Science and Technology (POSTECH) has devised an approach.

Their method combines three-dimensional nano printing with co-assembly technology, bringing metamaterials one step closer to becoming commercially available. These research findings have been featured in Small.
