A team of researchers from the Massachusetts Institute of Technology (MIT) has developed a framework for designing electromagnetic absorbers that are more efficient at absorbing electromagnetic waves than those currently available. The new absorbers are made of layered nanostructured materials, which are made up of multiple layers of metal, dielectric, and semiconductor materials. The layers are designed to interact with incoming radiation in a way that allows the absorber to capture more of the incident energy than traditional absorbers. The team believes that this new framework could lead to the development of more efficient and cost-effective absorbers for a variety of applications, including solar energy, stealth technologies, and wireless communications.
