An international team of researchers has just done the seemingly impossible: generate terahertz (THz) waves from water. Terahertz waves are a type of radiation with a wavelength shorter than ...

Xi-Cheng Zhang has worked for nearly a decade to solve a scientific puzzle that many in the research community believed to be impossible: producing terahertz waves--a form of electromagnetic radiation ...

One way to generate terahertz waves is with a CMOS chip-based amplifier-multiplier chain that increases the frequency of radio waves until they reach the terahertz range. To achieve the best ...
