Researchers Take Terahertz Data Links Around the Bend

Brown University researchers investigate how terahertz waves propagate and bounce off objects.

A new study shows terahertz data links are possible even without direct line of sight between transmitter and receiver.

Researchers at Brown University in Rhode Island recently conducted a study showing terahertz frequency data links can bounce around a room without losing too much data, which could make future terahertz wireless data networks more feasible.

Most terahertz researchers assumed there would be too much power loss when terahertz waves bounced off walls, but the Brown team has determined that the loss is actually quite tolerable in some cases.

The researchers bounced terahertz waves at four different frequencies off a variety of objects, and measured the bit-error-rate of the data on the wave after the bounces.

The researchers say they also conducted several outdoor experiments on terahertz wireless links.

Brown professor Daniel Mittleman notes these kinds of basic studies on the nature of terahertz data transmission are important for understanding how to design the network architecture for future terahertz data systems.
