#Underused part of the electromagnetic spectrum gets optics boost from metamaterial
“#Underused part of the electromagnetic spectrum gets optics boost from metamaterial” Terahertz metasurface ultra-thin collimator for power enhancement Credit: Takehito Suzuki, TUAT Terahertz radiation, or T-rays, has barely been exploited compared to most of the rest of the electromagnetic spectrum. Yet T-rays potentially have applications in next-generation wireless communications (6G/7G), security systems, biomedicine, and even…
