Cluster scientists, including Postdoctoral Researcher Yi Chen, Doctoral Researchers Jonathan L. G. Schneider, Ke Wang and Sebastian Kalt, and Principal Investigator Martin Wegener, have studied the fascinating properties of frozen evanescent waves in elastic metamaterials. Their findings show how these waves enable unique material responses and challenge Saint Venant’s principle, suggesting forces can have long-range effects. This research, published in Nature Communications, opens new possibilities for mechanical sensing and material design.
