Terahertz electromagnetic waves occupy a middle ground between electronics waves, like microwave and radio waves, and photonics waves, such as infrared and UV waves. For example, mobile phones use ...
Faster long-distance data transmission is a step closer, according to a team of Chinese scientists who say they have transmitted high-definition video signals over more than a kilometre using ...
Terahertz technology seems set to become important in security screening and the pharmaceutical industry. The ultimate solution for airport security would be a system that not only tells security ...
Researchers have created a wide range of optical elements that allow the manipulation of terahertz laser radiation. According to them, silicon and diamond diffractive optical elements for the ...
At wavelengths slightly longer than red, we get infrared radiation, and beyond that we get terahertz radiation and then microwaves. Light with the longest wavelengths – millimetres, metres or ...
When we then shot terahertz pulses at the material, the trions formed back into excitons extremely quickly. We were able to show it because excitons and trions emitted near-infrared radiation at ...
Radioactive materials are elements that spontaneously break apart, or “decay,” into lighter elements over time. Radiation is energy that’s released during that process—and it can be dangerous. What ...
