A team of researchers in the US (Brown University, industry) tested sending extremely high-frequency 200 GHz signals through a device with two wires running parallel inside a sheath with a large diameter that facilitates increased mixing of the waveguide modes. These mixtures enable the transmission of parallel noninterfering data channels. They demonstrated that the waveguide could support a data rate of 10 terabits per second. Their work demonstrates the feasibility of this approach to high-rate data transmission…read more.
A 13- by 13-millimeter measurement for each of the 169 possible locations of the signal input location of the waveguide. These measurements reveal multiple maxima in each 13×13 spot… Credit: The authors
