![]() ![]() It could yield ancillary benefits as well. His team has investigated both active and passive cloaking, the former a broadband solution that covers all mechanical waves and the latter a tailored solution wherein the metamaterial can be tuned to protect structures (like components) from specific mechanical wave frequencies.Ĭloaking smaller objects like components or pieces of soldier equipment - helmets, armor vests, boots, communications gear or weapons – would seem a logical early application for metamaterial once the science advances enough to get there. ![]() If you can develop that can shield or cloak mechanical vibration, even at particular frequencies, then you could potentially reduce fatigue damage to sensitive parts.”ĭr. “We spend a lot time replacing components within those structures. There, research discussions commonly centered on aerospace structures, on helicopters and fatigue life. We still have a lot of work to do.”ĭan Cole calls the Missouri metamaterial “potentially foundational.” He came to his current post from ARL’s Vehicle Technology Directorate at Aberdeen Proving Ground. So far, it’s theoretically possible but it’s difficult to fabricate. “If you want to cloak a submarine, then you need to cover its whole area. ![]() Getting bigger than that would be an effort, he admits. In fact the professor affirms that he could cloak a one meter-sized object right now. Huang asserts that his team’s metamaterial design could be “a nearly perfect protective device.” In addition to its conformal character it is potentially scale-able. of Missouri College of Engineering University of Missouriĭr.
