Taking terahertz data links around the bend

Science Daily  February 6, 2018
Unlike microwaves, terahertz waves are entirely blocked by most solid objects. The assumption has been that it’s not possible to bounce a terahertz beam around — say, off a wall or two — to find a clear path around an object. A team of researchers in the US (Brown University, New Jersey Institute of Technology) bounced terahertz waves at four different frequencies off a variety of objects and showed that acceptable bit-error-rates were achievable with modest increases in signal power… read more.

New research shows that non-line-of-site terahertz data links are possible because the waves can bounce off walls without losing too much data. Credit: Mittleman lab / Brown University
