摘要：
Excitation of surface plasmon–polariton (SPP) waves guided by the planar interface of a metal and an isotropic chiral material was investigated in the prism-coupled configurations. The characteristics of the SPP waves in both the Turbadar–Kretschmann–Raether configuration and the Turbadar–Otto configuration were studied. The results for SPP-wave excitation in the latter configuration were easily discernible than the former. The associated canonical boundary-value problem was numerically solved for the confirmation of the results of the prism-coupled configurations. It was seen that the SPP waves can exist only if the chirality pseudo-scalar has magnitude that is less than a threshold value.
