Spoof surface plasmon

ID: spoof-surface-plasmon

Spoof surface plasmons, also known as spoof plasmons or surface plasmon polaritons (SPPs) on structured surfaces, are electromagnetic waves that mimic the behavior of surface plasmons, which are collective oscillations of free electrons at the interface between a conductor and dielectric. However, spoof surface plasmons are realized in materials that do not necessarily have the free-electron characteristics typically required for conventional surface plasmons.
