摘要Spoof plasmonics,with unique quasi-optical and quasi-electrical properties,have emerged as a promising route toward compact,high-speed,and CMOS-compatible devices for next-generation integrated systems.A key requirement for advancing such circuits is nonreciprocal functionality,which enables signal routing,source protection,and suppression of backscattering.Conventional nonreciprocal schemes,however,typically rely on bulky magnetic components that lack tunability and remain incompatible with compact integrated platforms.
