A widely held understanding of electromagnetic radiation has been challenged in newly published research led at the University of Strathclyde.
The study found that the normal direct correspondence between the bandwidths of the current source and emitted radiation can be broken. This was achieved by extracting narrowband radiation with high efficiency, without making the oscillation of the current narrowband.
The finding produced narrowband light sources in media where electromagnetic radiation would not normally be possible. It makes for a powerful tool for scientists that enables them to understand the intricacies of how materials, or even biological molecules, behave under different conditions, which has a major impact on people's lives through the development of new products and medical treatments.
The research, published in Scientific Reports, also involved researchers at the Ulsan National Institute of Science and Technology (UNIST) and the Gwangju Institute of Science and Technology (GIST), both in South Korea.
