Tiny antenna enables portable biomedicine, food analysis, and other 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. The problem with the technology is that THz devices will require miniaturization before they can be more widely adopted. The recent study in Scientific Reports makes an important contribution to that effort.
