  • Although there are many reports on the development of devices for terahertz signal processing, the possibility of electrical control of the functionality remains elusive. Here, the authors use electrically actuated liquid metal components incorporated into terahertz waveguides for controlling power flow and for frequency filtering.

  • At terahertz frequencies, link discovery by scanning is impractically slow. Here, the authors propose an alternative, single-shot link-finding method based on a leaky-wave device.

  • As wireless communications move towards terahertz frequencies, previously unidentified jamming vulnerabilities are revealed. Novel features not typically observed at lower frequencies are studied, including high directional attacks, beat jamming and asymmetric bit interference.

  • ‘Hardy’ Helicobacter pylori ecospecies shares the ancestry of ‘Ubiquitous’ H. pylori from the same region in most of the genome but has nearly fixed single-nucleotide polymorphism differences in 100 genes.

  • Contrary to current expectation, eavesdropping on terahertz wireless data links is shown to be easier than expected, by placing an object in the path of the signal that scatters part of it to a receiver located elsewhere.

  • Hichem Guerboukha and colleagues describe a conformal (or curved) leaky waveguide in the THz range for antenna applications in wireless communications. The authors describe rich wave behavior at THz frequencies. They also experimentally show application potential for their antennas as multi-beam high-gain transmitters of wireless links with low bit error rates.
