Brown University joins mmW Coalition

Brown University has joined the MillimeterWave Coalition. This membership, initiated by Professor Mittleman and his group at Brown, enables the University to join other universities and companies in the effort to develop a favorable regulatory environment for systems employing terahertz radiation. According to the web page of the Coalition, “The mmWave Coalition is a group of innovative companies united in the objective of removing regulatory barriers to technologies and using frequencies ranging from 95 GHz to 450 GHz. The Coalition does not limit itself to supporting any particular use or technology but rather it is working to create a regulatory structure for these frequencies that would encompass all technologies and all possible uses, limited only by the constraints of physics, innovation, and the imagination.”

The membership list of the Coalition can be found here.

Imaging ancient ceramic pottery sherds using terahertz radiation

We can combine visible and THz imaging to extract quantitative metrics for density variations in ancient ceramic sherds! The publication can be found by clicking here.

Eavesdropping on terahertz wireless links

Our new paper shows that terahertz wireless data links aren’t as immune to eavesdropping as many researchers have assumed. The research, published in the journal Nature, shows that it is possible for a clever eavesdropper to intercept a signal from a terahertz transmitter without the intrusion being detected at the receiver. This work is a collaboration between our group and researchers at Rice University and at the University at Buffalo.
