摘要

Surface plasmon polaritons (SPPs) and their low-frequency counterpart spoof SPPs have attracted intensive interests in sciences [1,2],due to their unprecedented capabilities to confine electromagnetic (EM) fields at deep-subwavelength scale,leading to many applications such as super-resolution imaging [3],plasmonic lasers [4],surfaced-enhanced Raman effect [5],plasmonic waveguides [6,7] or circuits [8],etc.
