This Letter revises the resonance theory of Kretschmann and Otto configurations, where enhanced electromagnetic fields and strong reflectance dips observed under total internal reflection are conventionally attributed to the resonance on surface plasmon-polaritons, the subsystem eigenwaves supported by a single metal/dielectric interface. The rigorous mathematical analysis demonstrates that the field enhancement and reflection decrease, in fact, are two independent physical phenomena that occur under different conditions. Moreover, neither of them coincides with the resonance on surface plasmon-polaritons that manifests in Kretschmann and Otto configurations through other distinct optical effect.
本信函修正了克雷奇曼配置和奥托配置的共振理论，在全内反射下观察到的增强电磁场和强反射率凹陷通常归因于表面等离激元极化激元的共振，表面等离激元极化激元是由单个金属/介质界面支持的子系统本征波。严格的数学分析表明，场增强和反射率降低实际上是在不同条件下发生的两个独立物理现象。此外，它们都与通过其他明显光学效应在克雷奇曼配置和奥托配置中表现出来的表面等离激元极化激元的共振不一致。
