A single drop of blood is teeming with microorganisms—imagine if we could see them, and even nanometer-sized viruses, with the naked eye. That’s a real possibility with what scientists call a “perfect lens.” The lens hasn’t been created yet, but it is a theoretical perfected optical lens made out of metamaterials, which are engineered to change the way the materials interact with light.
While a perfect lens—and the metamaterials it’s made of—is almost perfect, it’s not foolproof. As the field of research expanded in the past 15 years, more and more challenges arose.
Now, researchers at Michigan Technological Univ. have found a way to possibly solve one of the biggest challenges, getting light waves to pass through the lens without getting consumed. The journal Physical Review Letters published their study, a continuation of work done by Durdu Güney, a professor of electrical and computer engineering at Michigan Tech.
