Carrying data streams using the terahertz (THz) spectral region could meet the ever-growing demand for unprecedented data transfer rates, i.e. terabits-per-second (Tb/s), since it offers a higher available bandwidth. However, it is extremely challenging to develop physical components that go beyond the most elementary processing functionalities for constructing future communication systems at THz frequencies. Scientists have now developed a new waveguide to overcome those limitations.
