Terahertz waves, which have the potential to outperform 5G as a method of wireless networks, have had a breakthrough recently. A team of experts from a German-Spanish research team and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have developed a material system that can generate terahertz pulses from gigahertz pulses more effectively than ever before.
This breakthrough was spurred by the team discovering that graphene can be used as a frequency multiplier, turning lower terahertz frequencies to higher ones. The material system composes of graphene, coated with a metallic lamellar structure. This system, being much smaller and attainable than the full-scale particle accelerators used before, have the potential to allow for simpler, more attainable terahertz magnifiers.
