The growing demand for high-speed and energy-efficient 5G communication systems is driving the need for higher frequency band adaptation of radio frequency (RF) communication devices. In this context of higher frequency band transition, semi-conductor-based power limiter shows significant noise and switching delays when operating in the EU 5G high band (24.25\u201327.5 GHz).<\/p>\n\n\n\n

To address this issue, a group of researchers of the University of Vienna has developed nanoscale frequency limiters based on spin wave transmission fabricated on a 97-nm thin yttrium iron garnet (YIG) film. Their system takes advantage of the four-magnon scattering process, for which a pair of magnons is excited by the input transducer and scatter into a second pair of magnons. The second pair then propagate in a different direction than the primary one, therefore impeding their detection by the output transducer.<\/p>\n\n\n\n
