Near-field chiral excitation of universal spin-momentum locking transport of edge waves in microwave metamaterials

Abstract: Controlling energy flow in waveguides has attractive potential in integrated devices from radio frequencies to optical bands. Due to the spin-orbit coupling, the mirror symmetry will be broken, and the handedness of the near-field source will determine the direction of energy transport. Compared with well-established theories about spin-momentum locking, experimental visualization of unidirectional coupling is usually challenging due to the lack of generic chiral sources and the strict environmental requiremen… Show more

“…In the case of spoof surface-plasmon polaritons, we encounter such a low-frequency cut-off which arises from sort of energy coupling (energy redistribution). Besides, we recognize in [31] the importance of the nearfield parameters for understanding a SOC taking place along material interfaces [10,13]. In an analogous line reasoning, a low-frequency cut-off takes place also in case of surface plasmon polaritons at a chiral-metal interface [22], which certainly involve SOCs.…”

“…These effects may involve matters, electrons, or photons [27], [32]. Interference effects arising from differential rotations employed by a Sagnac loop [31] bear resemblance to a counter-rotating pair of a left wave and right wave on the circular basis as examined in this study. By suitable Sagnac-loop-like configurations, SOCs can thus be manipulated to improve the interference visibility [27].…”

“…21–23,34–36 However, to date plentiful metasurfaces concentrate on the manipulation of PWs, while the manipulation of SWs through metasurfaces is not common. There is some research about the excitation and manipulation methods of SWs, including the helicity-dependent directional coupling of SWs, 44,45 spin-momentum locking excitation of edge waves 49 and spoof surface plasmon polaritons, 50 and deflection or focusing of SWs. 19,20,46 However, most previous studies only focus on the directional coupling of SWs 44,45,49,50 or the formation of merely several kinds of structured SWs.…”
