Hyperbolic Metamaterial Waveguide for Rainbow Trapping

Buffalo University researchers have created an advanced waveguide which could lead to breakthroughs in stealth technology and solar energy. Their hyperbolic metamaterial waveguide is basically a sophisticated microchip made from alternating ultra-thin films of metal and semiconductors and/or insulators. The waveguide stops and eventually absorbs every light frequency, at somewhat different points in a vertical axis, to capture a rainbow of wavelengths. “Electromagnetic absorbers have been studied for many years, especially for military radar systems,” said Qiaoqiang Gan, PhD, an assistant professor at UB,.
