Researchers Make Transparent Materials Absorb Light

Researchers have demonstrated an optical paradox – they have made a completely transparent material appear perfectly light-absorbing. The results of their research contradict the idea that materials that look transparent, such as glass, appear that way because they have no light-absorbing qualities. Based on their results, researchers introduce the concept of coherent virtual absorption in a lossless electromagnetic system, a phenomenon that arises when the incident electromagnetic field matches the spatiotemporal distribution of a complex scattering zero of a lossless system.
