Carbon nanotube 'black paint' absorbs terahertz radiation to cut 6G interference
Skoltech researchers and their colleagues from KTH Royal Institute of Technology, Sweden, have created an important building block for future 6G communication technology, which will make wireless data transfer at superior transmission rates possible. The newly developed piece of the 6G puzzle is not a device component, but a carbon nanotube-based black paint of sorts that thoroughly absorbs electromagnetic radiation wherever its transmission would be detrimental. The study was published in Nature Communications. Occupying the middle ground between infrared light used in night vision and microwaves used to heat your lunch, terahertz radiation is a promising band of electromagnetic waves for 6G communication, advanced biomedical imaging and sensing.
