Superconducting Niobium Waveguide Achieves High‐precision Communications for B5G/6G Networks


A group led by researchers at Nagoya University has discovered how to speed up the transition of Beyond 5G/6G signals using a three‐dimensional circuit based on the superconducting metal niobium. Although niobium is considered a difficult‐to‐machine material, the group was able to create a waveguide in the millimetre wavelength range with high precision.

The study, “Propagation in Superconducting Niobium Rectangular Waveguide in the 100 GHz band,” has been published in Journal of Physics: Conference Series at DOI: 10.1088/1742-6596/2545/1/012021.
