Tiny antenna enables portable biomedical, food-analysis, and other gadgets driven by integrated nano- and terahertz technologies

A Skoltech professor and his colleagues from Germany have designed a very small and flat antenna for receiving and transmitting terahertz signals. THz waves are a band of electromagnetic radiation that holds much promise for applications as diverse as security checks and wireless communication, cancer screening and dentistry, and detection of food degradation and defects in manufactured devices.
