Nanowerk  June 15, 2021 Previously researchers succeeded in demonstrating the phenomenon of perfect absorption in large bodies of matter that were several times the size of a light beam. But the question remained unsolved was – whether the same was possible for miniature objects. An international team of researchers (Russia, Sweden) calculated the properties of a small object that could completely absorb all incidental light. They succeeded in reducing this complex analytical task to a simpler one – a Fredholm integral equation of the second kind. Having solved it, they found the ideal combination of particle and light properties that […]
