Researchers Find Practical Way for Tuning Terahertz Quantum Cascade Lasers

For more than 30 years, scientists have been trying to harness the power of terahertz radiation. Tucked between microwaves and infrared rays on the electromagnetic spectrum, terahertz rays can penetrate clothing, plastic, and human tissue, but they're thought to be safer than x-rays. Since they're absorbed to different degrees by different molecules, they can also tell chemicals apart: a terahertz scanner at an airport checkpoint, for example, could determine whether a vial in a closed suitcase contained aspirin, methamphetamines or an explosive.

Rice University Researchers Find Plasmonic Material That Let Pass Terahertz Beam Completely

Very often in science, the unexpected discovery turns out to be the most significant. Rice University Professor Junichiro Kono and his team weren't looking for a breakthrough in the transmission of terahertz signals, but there it was: a plasmonic material that would, with adjustments to its temperature and/or magnetic field, either stop a terahertz beam cold or let it pass completely.
