Graphical Abstract Ultra-Wideband Dynamic Microwave Frequency Identification System In article number 2400332, Guanghui Ren, Yonghui Tian, and co-workers experimentally demonstrate an integrated ultra-wideband dynamic microwave frequency identification system in lithium niobate on insulator (LNOI). The bandwidth of microwave frequency systems is extended to millimeter-wave U-band using the excellent electro-optical properties of lithium niobate.
