News Finding: The implications are enormous.
Paper Finding: The 1 dB insertion loss bandwidth in S 21 and S 32 is 4.6 GHz (18.4%), and the S 31 isolation over this bandwidth ranges from −18.3 to −20.2 dB.
News Context: "This mm-wave circulator enables mm-wave wireless full-duplex communications," Krishnaswamy adds, "and this could revolutionize emerging 5G cellular networks, wireless links for virtual reality, and automotive radar." The implications are enormous. These radars inherently need to be full-duplex, and would work alongside ultra-sound and camera-based sensors in self-driving cars because they can work in all weather conditions and during both night and day.
Paper Context: T s =1/f s Fig. The 1 dB insertion loss bandwidth in S 21 and S 32 is 4.6 GHz (18.4%), and the S 31 isolation over this bandwidth ranges from −18.3 to −20.2 dB. This is notably wideband compared with prior art, including −20 dB S 31 isolation bandwidths of 4.2% in ref.
