A metamaterial is an engineered material whose structure, rather than its chemical make-up alone, gives it unusual properties, for example in how it bends light, radio waves or sound. In the UFO field the term is associated with claims that fragments of crashed craft are layered alien metamaterials — claims that U.S. government testing of one such sample did not support.[1][2]

Metamaterials are built from repeating structures smaller than the wavelengths they affect, allowing effects not found in natural materials, such as negative refraction, and they are used in research on antennas, lenses and experimental "invisibility cloaks".[1]

The To The Stars sample

In 2019 To The Stars Academy of Arts & Sciences, which said it had acquired metal pieces of possibly non-terrestrial origin, signed a five-year research agreement with the U.S. Army's Ground Vehicle Systems Center. The only item it submitted was a magnesium-zinc-bismuth sample known as "Artifact A1", which it claimed could act as an electromagnetic waveguide, based on published theoretical designs.[2][3]

Test results

The Army worked with Oak Ridge National Laboratory and the Pentagon's All-domain Anomaly Resolution Office (AARO). Oak Ridge received the sample in June 2021 and carried out structural, compositional and isotopic analyses. It found that the sample lacked the structure needed to act as a waveguide, had inconsistent layers, and was probably made with commercial techniques, likely as a test object or aerospace-related material. The Army's close-out report said the sample was not of unknown origin and showed no exotic properties. To The Stars acknowledged the findings in brief statements.[2]
