SOLAR - Captured Rainbows, New Possibilities In Solar Energy Thanks To New Material That Slows Light

An improved method to capture rainbows has been developed by researchers at the University at Buffalo. The photonics breakthrough could very likely lead to significant improvements in solar energy, stealth technologies, and other areas of research, according to the researchers.The researchers created a "hyperbolic metamaterial waveguide," that works to separate and absorb every frequency of light at different locations in a vertical direction, ...
