Electromagnetic-circuit co-design approach leads to dynamically programmable holographic terahertz metasurfaces
The programmable surface, called a metasurface, allows engineers to dynamically control and focus transmissions in the terahertz band of the electromagnetic spectrum. Credit: Suresh Venkatesh With the help of integrated CMOS technology and electromagnetic design, Princeton researchers have demonstrated a key device that could potentially enable high-speed wireless links at terahertz frequencies. Metasurfaces, which consist […]
