A coat has been created that protects against microwaves

Scientists from a US-British team have presented a novel cloak that provides invisibility from microwaves, which has been successfully tested at a Duke University laboratory. The device, classified as a metamaterial, works by reflecting microwaves around the object being concealed, significantly reducing its visibility. While this technology opens new perspectives in the field of electromagnetism, the creators emphasize that achieving complete invisibility from visible light still requires further research and development of nanotechnology.

A US-British team of scientists has successfully tested an invisibility cloak in the laboratory. During tests at Duke University in North Carolina (USA), the device typically hid a small copper disc from microwaves. This works by reflecting microwaves around an object and redirecting them in a different direction, as if passing through empty space. However, hiding an object from view remains a science fiction dream.

The cladding consists of 10 fiberglass rings covered with copper elements and has been classified as a "metamaterial" - an artificial interconnection designed specifically to induce desired changes in electromagnetic waves.

As with visible light waves, the reflection of microwaves on an object makes it visible and creates a shadow. However, at microwave frequencies, detecting objects must be done with instruments, not the naked eye.
