The use of atomic arrays to achieve negative refraction has been confirmed for the first time, which is expected to promote the development of superlenses and stealth technology

On February 14th, scientists from Lancaster University in the UK and Japan Telegraph and Telephone Company confirmed for the first time that negative refraction can be achieved using an atomic array without relying on artificially manufactured “metamaterials”. This discovery paves the way for the development of superlenses and new stealth devices. The relevant paper was published in the journal Nature Communications on the 12th.
